Text reads 'Pet of the day... ' Below is a notice tacked to a wall which has an image of a cat wearing spectacles on it. Text reads 'LOST. Large moggy, last seen roaming in Christchurch. Answers to the name of "Gerry" or "Dinners ready". Has a loud purr, looks cuddly but can turn...' Context: This is a reference to Gerry Brownlee, the Minister for Earthquake Recovery. When National announced its offer based on the 2007 rating valuation to red-zone property owners on 23 June, Gerry Brownlee specifically told people who had made improvements between the time of the valuation and the September quake to 'keep their receipts'. The offer from CERA dated August 19 now says quite clearly that people can only seek an adjustment to the purchase price if the rating valuation is based on an incorrect floor area, or if 'you have received a code compliance certificate for consented building work undertaken after the rating valuation and that work increased the floor area of your house'.

A dramatic consequence of the Christchurch, New Zealand, earthquakes of 2010 and 2011 was the widespread liquefaction in the city. Part of the central business district (CBD) was badly affected by liquefaction but elsewhere large volumes of ejecta were not evident for those parts of the CBD where the upper layers in the soil profile are sandy gravel and gravelly sand. The purpose of the paper is to investigate the effect of the gravel permeability on the rise and dissipation of excess pore water pressure during cyclic loading of a soil profile idealised from Christchurch data. The Cyclic1D software, which performs one-dimensional non-linear effective stress site response analysis, was used. Permeability values associated with gravel were found to suppress the cyclic accumulation of excess pore water pressure in gravel layers. Given that there has not been any systematic measurement of the in situ permeability of the gravels in Christchurch, the modelling in the paper suggests that likely values for the bulk permeability of the gravel layers are within the range suggested in the geotechnical literature. However, the work reported is of wider application than Christchurch and emphasises the controlling influence of permeability on the accumulation and dissipation of cyclic pore pressures.

Maori Party MP for Te Tai Tonga, Rahui Katene' is buried up to her neck in earthquake rubble as she reads a newspaper headline referring to her statement that the aftermath of the earthquake has demonstrated 'racism and ethnic profiling'. Rahui Katene's head is disintegrating and two engineers who are examining the damage decide that 'This can't be repaired, it needs to be condemned'. Rahui Katene says the authorities, who kicked a Christchurch family out of a welfare centre that was set up after the Christchurch earthquake that struck on the 4th September, should apologise for judging them too early and shaming them publicly. Mrs Katene was also concerned about claims that Maori youth were being targeted by police. "I've heard from whanau that in one particular area rangatahi who were volunteering in their community and helping their whanau were accused by police of theft. The whanau are trying to work these issues through with the police, but I'm growing concerned about what appears to be ethnic profiling." Quantity: 1 digital cartoon(s).

Minister for Social Development Paula Bennett stands on a large carpet that represents the 'dole'; she has swept the detritus of 'job initiatives', 'unemployment' and 'job summit' under the carpet with a broom and says 'The benefit system is there and can sort of get as big as it needs to' Context - the Government has announced its business assistance package to Christchurch is to be watered down and then cease over the next few weeks. John Key and Paula Bennett have said that 'the dole will be there for them'. Clayton Cosgrove Labour's Canterbury Earthquake Recovery spokesperson says Prime Minister John Key and Social Development Minister Paula Bennett are cruelly missing the point in terms of Canterbury people who lose their jobs in the wake of the earthquakes. He says "They want jobs, and they want to know what the Government is going to do about ensuring Christchurch businesses can get up and running again".

For some people, religion, spirituality and faith (RSF) serves an important function, helping them deal with difficult everyday life challenges. This qualitative ethnographic study examines how and in what ways a group of Cantabrians engaged with RSF in dealing with diverse forms of significant trauma – from moments of crisis through to more extended processes of recovery. The research is located within the context of post-earthquake Christchurch, and is based on fieldwork undertaken in 2012–2013. It explores the experiences of respondents representing traditional Christian and non-orthodox, non-Christian faith paths. The thesis draws on data from participant stories to emphasise the subjective experience of RSF and trauma. It argues that in times of crisis, some people draw on RSF to help them address difficult life challenges. The study demonstrates the breadth, diversity and significance of such resourcing, as well as the sometimes surprising, unanticipated forms that this engagement with RSF may take. Contrary to theories that emphasise the marginalisation of religion during times of intense distress, the thesis shows that in varying moments of crisis, people for whom RSF is important, may draw on diverse forms of RSF as a matter of priority to help them.

Earthquakes rupture not only the objective realm of the physical landscape, but also the subjective landscape of emotions. Using the concepts of topophilia and topophobia developed by Yi-Fu Tuan as theories of love and fear of place, this paper investigates the impact of Christchurch’s earthquakes of 2010 and 2011 on relationships with the city’s landscape. Published accounts of the earthquakes in newspapers from around New Zealand are examined for evidence of how people responded to the situation, in particular their shifting relationship with familiar landscapes. The reports illustrate how residents and visitors reacted to the actual and perceived changes to their surroundings, grappling with how a familiar place had become alien and often startling. The extreme nature of the event and the death toll of 185 heightened perceptions of the landscape, and even the most taken-for-granted elements of the landscape became amplified in significance. Enhanced understanding of the landscape of emotions is a vital component of wellbeing. Through recognising that the impact of disasters and perceived threats to familiar places has a profound emotional effect, the significance of sense of place to wellbeing can be appreciated.

The aim of this report is to investigate the ductile performance of concrete tilt-up panels reinforced with cold-drawn mesh to improve the current seismic assessment procedure. The commercial impact of the project was also investigated. Engineering Advisory Group (EAG) guidelines state that a crack in a panel under face loading may be sufficient to fracture the mesh. The comments made by EAG regarding the performance of cold-drawn mesh may be interpreted as suggesting that assessment of such panels be conducted with a ductility of 1.0. Observations of tilt-up panel performance following the Christchurch earthquakes suggest that a ductility higher than μ=1.0 is likely to be appropriate for the response of panels to out-of-plane loading. An experimental test frame was designed to subject ten tilt-panel specimens to a cyclic quasi-static loading protocol. Rotation ductility, calculated from the force-displacement response from the test specimens, was found to range between 2.9 and 5.8. Correlation between tensile tests on 663L mesh, and data collected from instrumentation during testing confirmed that the mesh behaves as un-bonded over the pitch length of 150mm. Recommendation: Based on a moment-rotation assessment approach with an un-bonded length equal to the pitch of the mesh, a rotation ductility of μ=2.5 appears to be appropriate for the seismic assessment of panels reinforced with cold-drawn mesh.

Following the recent earthquakes in Chile (2010) and New Zealand (2010/2011), peculiar failure modes were observed in Reinforced Concrete (RC) walls. These observations have raised a global concern on the contribution of bi-directional loading to these failure mechanisms. One of the failure modes that could potentially result from bidirectional excitations is out-of-plane shear failure. In this paper an overview of the recent experimental and numerical findings regarding out-of-plane shear failure in RC walls are presented. The numerical study presents the Finite Element (FE) simulation of wall D5-6 from the Grand Chancellor Hotel that failed in shear in the out-of-plane direction in the February 2011 Christchurch earthquake. The main objective of the numerical study was to investigate the reasons for this failure mode. The experimental campaign includes the recent experiments conducted in the Structural Engineering Laboratory of the University of Canterbury. The experimental study included three rectangular slender RC walls designed based on NZS3101: 2006-A3 (2017) for three different ductility levels, namely: nominally ductile, limited ductile and ductile. The numerical results showed that high axial load combined with bi-directional loading caused the out-of-plane shear failure in wall D5-6 from the Grand Chancellor Hotel. This was also confirmed and further investigated in the experimental phase of the study.

The Townsend Observatory is located in the Arts Centre of Christchurch, in what used to be Canterbury College (now University of Canterbury). The Townsend telescope itself is a historic 6-inch Cooke refractor built in 1864 for early Christchurch colonist, Mr James Townsend, and gifted by him to Christchurch College in 1891. At the same time, the Canterbury Astronomical Society handed over its funds to the College to help erect an observatory. The College used this, and money it had set aside for a medical school, to build a biological laboratory with an attached observatory tower, which was completed in 1896. The Biology Building and Observatory Tower was the last major design by architect Benjamin Mountfort. Mr Walter Kitson was appointed custodian of the telescope and regular public open nights commenced. and continued until 2010, with the telescope being operated by students of the Department of Physics and Astronomy, University of Canterbury. The Observatory Tower was badly damaged in the 4 September 2010 earthquake and collapsed in the 22 February 2011 earthquake. The telescope was badly damaged by the collapse, but, amazingly, the optics were found entirely intact. The Department of Physics and Astronomy plans to restore the Townsend Telescope so that it can be returned to a replica Observatory Tower in its central city home, enabling the people of Christchurch, and visitors, to enjoy views of the night sky through this beautiful and historic telescope once again.

A video of a presentation by Dr Lesley Campbell during the Community and Social Recovery Stream of the 2016 People in Disasters Conference. The presentation is titled, "Canterbury Family Violence Collaboration: An innovative response to family violence following the Canterbury earthquakes - successes, challenges, and achievements".The abstract for this presentation reads as follows: Across a range of international jurisdictions there is growing evidence that shows a high prevalence of family violence, child abuse and sexual violence over a number of years following natural disasters (World Health Organisation, 2005). Such empirical findings were also reflected within the Canterbury region following the earthquake events in 2010 and 2011. For example, in the weekend following the September 2010 earthquake, Canterbury police reported a 53% increase in call-outs to family violence incidents. In 2012, Canterbury police investigated over 7,400 incidents involving family violence - approximately 19 incidents each day. Child, youth and family data also reflect an increase in family violence, with substantiated cases of abuse increasing markedly from 1,130 cases in 2009 to 1,650 cases in 2011. These numbers remain elevated. Challenging events like the Canterbury earthquakes highlight the importance of, and provide the catalyst for, strengthening connections with various communities of interest to explore new ways of responding to the complex issue of family violence. It was within this context that the Canterbury Family Violence Collaboration (Collaboration) emerged. Operating since 2012, the Collaboration now comprises 45 agencies from across governmental and non-governmental sectors. The Collaboration's value proposition is that it delivers system-wide responses to family violence that could not be achieved by any one agency. These responses are delivered within five strategic priority areas: housing, crisis response and intervention, prevention, youth, and staff learning and development. The purpose of this presentation is to describe the experiences of the collaborative effort and lessons learnt by the collaborative partners in the first three years after its establishment. It will explore the key successes and challenges of the collaborative effort, and outline the major results achieved - a unique contribution, in unique circumstances, to address family violence experienced by Canterbury people throughout the period of recovery and rebuild.

The whare whakairo or traditional Māori meeting house plays an important part in Māori society and identity. These whare tell the tale of their origin, and in so doing, the origins of their people. The analysis of the meeting house, the histories expressed in its decorative carvings and structural elements are inextricably linked with and dependent upon the structure of the world created by myth and the Māori worldview. However, due to the deleterious effects of colonisation, the art of wood carving and associated architectural practices - central to Māori identity, suffered decline in many parts of the country, leading to the decline of Māori culture and identity. Sir Apirana Ngata instigated the National Institute of Māori Arts and Crafts to resurrect the dying art of Māori carving and carved houses would be a catalyst for the restoration of Māori culture throughout the country. Ngata saw these whare whakairo as being the heart of Māori communities by establishing a renewed sense of belonging and identification with space for Māori, through the telling of tribal histories and emphasising key geographical features. New threats in the form of global hegemony and urbanisation have further impacted on Māori notions of identity, creating a generation of displaced urban Māori youth. This research proposes to establish an architectural response to capture displaced Māori youth through the resurrection of the Māori carving school and return to them the lost stories of their cultural history and identity. This program will be developed within the complex challenges that exist within post-earthquake Ōtautahi/Christchurch, where many have lost homes and livelihoods, especially Māori youth in the Eastern Suburbs. The building elements of the proposed Māori carving school give reference to the historio-cultural features of the original Ōtautahi/Christchurch landscape that are situated in tribal song and myth. It is envisioned that the development of a Māori carving school will help restore Māori identity and a renewed sense of belonging, and allow for the telling of this generations stories through traditional narratives.

A video of the keynote presentation by Sir John Holmes, during the first plenary of the 2016 People in Disasters Conference. Holmes is the former United Nations Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator, the current Director of Ditchley Foundation, and the chair of the Board of the International Rescue Committee in the UK. The presentation is titled, "The Politics of Humanity: Reflections on international aid in disasters".The abstract for this presentation reads as follows: As United Nations Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinate from 2007-2010, Sir John Holmes was heavily involved in the coordination of air provision to countries struck by natural and man-made disasters, raising the necessary funds, and the elaboration of humanitarian policy. The international humanitarian system is fragmented and struggling to cope with rising demands from both conflicts such as that in Syria, and the growing effects of climate change. Sir John will talk about what humanitarian aid can and cannot achieve, the frustrations of getting aid through when access may be difficult or denied, and the need to ensure that assistance encompasses protection of civilians and efforts to get them back on their feet, as well as the delivery of essential short term items such as food, water, medical care and shelter. He will discuss the challenges involved in trying to make the different agencies - UN United Nations, non-government organisations and the International Red Cross/Crescent movement - work together effectively. He will reveal some of the problems in dealing with donor and recipient governments who often have their own political and security agendas, and may be little interested in the necessary neutrality and independence of humanitarian aid. He will illustrate these points by practical examples of political and other dilemmas from aid provision in natural disasters such as Cyclone Nargis in Myanmar in 2009, and the Haiti earthquake of 2010, and in conflict situations such as Darfur, Afghanistan and Sri Lanka in the past, and Syria today. He will also draw conclusions and make recommendations about how humanitarian aid might work better, and why politicians and others need to understand more clearly the impartial space required by humanitarian agencies to operate properly.

Rocket Lab's Electron rocket launch today on the Mahia Peninsula has been scrubbed again, sadly. A power fault this time. Kaikoura residents and businesses are celebrating the re-opening of State Highway 1 north following a year of earthquake repairs. The coastal highway link between Picton and Christchurch was badly damaged during the November 2016 quake but will now re-open during the day from 7am. It will close at 8:30 each night so more repairs and assesments can be done. Kaikoura Top Ten Holiday Park co-owner Ed Nolan tells us what this means for his business and others in the town. The Prime Minister Jainda Ardern says the Government's new families package will reduce child poverty in the country by 48 per cent. We ask the panellists whether this is realistic or if there are other, more entrenched imprediments to lowering poverty in New Zealand. The panellists also discuss the state of the books, and discuss if they worry about national debt iincreasing, as the opposition has warned. The Prime Minister says wealthy New Zealanders can opt out of the Government's Winter Energy Payment, which will see those on a benefit, NZ Superannuation or a Veterans Pension get an extra boost due the winter season. Many are doubtful that will happen though. The panellists discuss why some wealthy people have missed out on tax cuts only to be able to reap the reward of this package. We also ask if they suspect this money will be used for heating purposes. The University of Otago has a new degree which brings science and art together, the BaSc. It aims to break down barriers between the two disciplines. Two students are graduating the degree this week. We talk to Eirenie Taua'i who has been studying Pacific Studies and Neuroscience. We aslk her what careers she is considering now and what it was like to study to very different courses. The families of those who died in the CTV building collapse in Christchurch's 2011 earthquake say they will continue to fight for justice. Police announced earlier this month they won't be prosecuting the engineers of the building after a three-year long investigation. The families met with police to ask and why say they aren't convinced all has been done. We ask panellist, barrister Jonathan Krebs, if other charges could and should be laid.

The aim of this thesis was to examine the spatial and the temporal patterns of anxiety and chest pain resulting from the Canterbury, New Zealand earthquaeks. Three research objectives were identified: examine any spatial or termporal clusters of anxiety and chest pain; examine the associations between anxiety, chest pain and damage to neighbourhood; and determine any statistically significant difference in counts of anxiety and chest pain after each earthquake or aftershock which resulted in severe damage. Measures of the extent of liquefaction the location of CERA red-zones were used as proxy measures for earthquake damage. Cases of those who presented to Christchurch Public Hospital Emergency Department with either anxiety or chest pain between May 2010 and April 2012 were aggregated to census area unit (CAU) level for analysis. This thesis has taken a unique approach to examining the spatial and spatio-temporal variations of anxiety and chest pain after an earthquake and offers unique results. This is the first study of its kind to use a GIS approach when examining Canterbury specific earthquake damage and health variables at a CAU level after the earthquakes. Through the use of spatio-termporal scan modelling, negative and linear regression modelling and temporal linear modelling with dummy variables this research was able to conclude there are significant spatial and temporal variations in anxiety and chest pain resulting from the earthquakes. The spatio-termporal scan modelling identified a hot cluster of both anxiety and chest pain within Christchurch at the same time the earthquakes occurred. The negative binomial model found liquefaction to be a stronger predictor of anxiety than the Canterbury Earthquake Recovery Authority's (CERA) land zones. The linear regression model foun chest pain to be positively associated with all measures of earthquake damage with the exception of being in the red-zone. The temporal modelling identified a significant increase in anxiety cases one month after a major earthquake, and chest pain cases spiked two weeks after an earthquake and gradually decreased over the following five weeks. This research was limited by lack of control period data, limited measures of earthquake damage, ethical restrictions, and the need for population tracking data. The findings of this research will be useful in the planning and allocation of mental wellbeing resources should another similar event like the Canterbury Earthquakes occur in New Zealand.

The Mw 6.2 February 22nd 2011 Christchurch earthquake (and others in the 2010-2011 Canterbury sequence) provided a unique opportunity to study the devastating effects of earthquakes first-hand and learn from them for future engineering applications. All major events in the Canterbury earthquake sequence caused widespread liquefaction throughout Christchurch’s eastern suburbs, particularly extensive and severe during the February 22nd event. Along large stretches of the Avon River banks (and to a lesser extent along the Heathcote) significant lateral spreading occurred, affecting bridges and the infrastructure they support. The first stage of this research involved conducting detailed field reconnaissance to document liquefaction and lateral spreading-induced damage to several case study bridges along the Avon River. The case study bridges cover a range of ages and construction types but all are reinforced concrete structures which have relatively short, stiff decks. These factors combined led to a characteristic deformation mechanism involving deck-pinning and abutment back-rotation with consequent damage to the abutment piles and slumping of the approaches. The second stage of the research involved using pseudo-static analysis, a simplified seismic modelling tool, to analyse two of the bridges. An advantage of pseudo-static analysis over more complicated modelling methods is that it uses conventional geotechnical data in its inputs, such as SPT blowcount and CPT cone resistance and local friction. Pseudo-static analysis can also be applied without excessive computational power or specialised knowledge, yet it has been shown to capture the basic mechanisms of pile behaviour. Single pile and whole bridge models were constructed for each bridge, and both cyclic and lateral spreading phases of loading were investigated. Parametric studies were carried out which varied the values of key parameters to identify their influence on pile response, and computed displacements and damages were compared with observations made in the field. It was shown that pseudo-static analysis was able to capture the characteristic damage mechanisms observed in the field, however the treatment of key parameters affecting pile response is of primary importance. Recommendations were made concerning the treatment of these governing parameters controlling pile response. In this way the future application of pseudo-static analysis as a tool for analysing and designing bridge pile foundations in liquefying and laterally spreading soils is enhanced.

On 14 November 2016, the Mw 7.8 Kaikōura earthquake caused widespread damage along the east coast of the South Island, New Zealand. Kaikōura town itself was isolated from the rest of the country by landslides blocking off major roads. While impacts from the Kaikōura earthquake on large, urban population centres have been generally well documented, this thesis aims to fill gaps in academic knowledge regarding small rural towns. This thesis investigates what, where and when critical infrastructure and lifeline service disruption occurred following the 2016 Kaikōura earthquake in a selection of small towns, and how the communities in these areas adapted to disruption. Following a robust review of literature and news media, four small rural towns were selected from North Canterbury (Culverden & Waiau) and Marlborough (Seddon & Ward) in the South Island, New Zealand. Semi-structured interview sessions with a special focus on these towns were held with infrastructure managers, emergency response and recovery officials, and organisation leaders with experience or expertise in the 2016 Kaikōura earthquake. Findings were supplemented with emergency management situation reports to produce hazard maps and infrastructure exposure maps. A more detailed analysis was conducted for Waiau involving interdependence analyses and a level of service timeline for select lifeline services. The earthquake impacted roads by blocking them with landslides, debris and surface rupture. Bridges where shaken off their abutments, breaking infrastructure links such as fibre landlines as they went. Water supplies and other forms of infrastructure relied heavily on the level of service of roads, as rough rural terrain left few alternatives. Adapting to an artificial loss of road service, some Waiau locals created their own detour around a road cordon in order to get home to family and farms. Performance of dwellings was tied to socioeconomic factors as much as proximity to the epicentre. Farmers who lost water access pulled out fences to allow stock to drink from rivers. Socioeconomic differences between farmland and township residents also contributed to resilience variations between the towns assessed in this study. Understanding how small rural towns respond and adapt to disaster allows emergency management officials and policy to be well informed and flexible with planning for multiple size classes of towns.

Post-tensioned timber technology was originally developed and researched at the University of Canterbury (UC) in New Zealand in 2005. It can provide a low-damage seismic design solution for multi-storey mass timber buildings. Since mass timber products, such as cross-laminated timber (CLT), have high in-plane stiffness, a post-tensioned timber shear wall will deform mainly in a rocking mechanism. The moment capacity of the wall at the base is commonly determined using the elastic form of the Modified Monolithic Beam Analogy (MMBA). In the calculation of the moment capacity at the wall base, it is critical to accurately predict the location of the neutral axis and the timber compressive stress distribution. Three 2/3 scale 8.6m tall post-tensioned CLT walls were experimentally tested under quasi-static cyclic loading – both uni-directional and bi-directional- in this study. These specimens included a single wall, a coupled wall, and a C-shaped core-wall. The main objective was to develop post-tensioned C-shaped timber core-walls for tall timber buildings with enhanced lateral strength and stiffness. To better understand the timber compressive stress distributions at the wall base, particle tracking technology (PTT) technology was applied for the first time to investigate the behaviour of the compression toe. Previous post-tensioned timber testing primarily used the displacement measurements to determine the timber compressive behavior at the wall base or rocking interfaces. However, by using PTT technology, the timber strain measurements in the compression zone can be much more accurate as PTT is able to track the movement of many particles on the timber surface. This paper presents experimental testing results of post-tensioned CLT walls with a focus on capturing timber compressive behavior using PTT. The PTT measurements were able to better capture small base rotations which occurred at the onset of gap opening and capture unexpected phenomena in core-wall tests. The single wall test result herein presented indicates that while the MMBA could predict the moment rotation behavior with reasonable accuracy, the peak strain response was under predicted in the compression toe. Further detailed study is required to better understand the complex strain fields generated reflective of the inherent cross-thickness inhomogeneity and material variability of CLT.

This thesis explores how social entrepreneurship develops following a crisis. A review of literature finds that despite more than 15 years of academic attention, a common definition of social entrepreneurship remains elusive, with the field lacking the unified framework to set it apart as a specialised field of study. There are a variety of different conceptualisations of how social entrepreneurship works, and what it aims to achieve. The New Zealand context for social entrepreneurship is explored, finding that it receives little attention from the government and education sectors, despite its enormous potential. A lack of readily available information on social entrepreneurship leads most studies to investigate it as a phenomenon, and given the unique context of this research, it follows suit. Following from several authors’ recommendations that social entrepreneurship be subjected to further exploration, this is an exploratory, inductive study. A multiple case study is used to explore how social entrepreneurship develops following a natural disaster, using the example of the February 2011 earthquake in Christchurch, New Zealand. With little existing theory in this research area, this method is used to provide interesting examples of how the natural disaster, recognised as a crisis, can lead to business formation. Findings revealed the crisis initially triggered an altruistic response from social entrepreneurs, leading them to develop newly highlighted opportunities that were related to fields in which they had existing skills and expertise. In the process of developing these opportunities, initial altruistic motivations faded, with a new focus on the pursuit of a social mission and aims for survival and growth. The social missions addressed broad issues, and while they did address the crisis to differing extents, they were not confined to addressing its consequences. A framework is presented to explain how social entrepreneurship functions, once triggered in response to crisis. This framework supports existing literature that depicts social entrepreneurship as a continuous process, and illustrates the effects of a crisis as the catalyst for social business formation. In the aftermath of a crisis, when resources are likely to be scarce, social entrepreneurs play a significant role in the recovery process and their contributions should be highly valued both by government and relevant disaster response bodies. Policies that support social entrepreneurs and their ventures should be considered in the same way as commercial ventures.

This thesis addresses the topic of local bond behaviour in RC structures. The mechanism of bond refers to the composite action between deformed steel reinforcing bars and the surrounding concrete. Bond behaviour is an open research topic with a wide scope, particularly because bond it is such a fundamental concept to structural engineers. However, despite many bond-related research findings having wide applications, the primary contribution of this research is an experimental evaluation of the prominent features of local bond behaviour and the associated implications for the seismic performance of RC structures. The findings presented in this thesis attempt to address some structural engineering recommendations made by the Canterbury Earthquakes Royal Commission following the 2010-2011 Canterbury (New Zealand) earthquake sequence. A chapter of this thesis discusses the structural behaviour of flexure-dominated RC wall structures with an insufficient quantity of longitudinal reinforcement, among other in situ conditions, that causes material damage to predominantly occur at a single crack plane. In this particular case, the extent of concrete damage and bond deterioration adjacent to the crack plane will influence the ductility capacity that is effectively provided by the reinforcing steel. As a consequence of these in situ conditions, some lightly reinforced wall buildings in Christchurch lost their structural integrity due to brittle fracture of the longitudinal reinforcement. With these concerning post-earthquake observations in mind, there is the underlying intention that this thesis presents experimental evidence of bond behaviour that allows structural engineers to re-assess their confidence levels for the ability of lightly reinforced concrete structures to achieve the life-safety seismic performance objective the ultimate limit state. Three chapters of this thesis are devoted to the experimental work that was conducted as the main contribution of this research. Critical details of the experimental design, bond testing method and test programme are reported. The bond stress-slip relationship was studied through 75 bond pull-out tests. In order to measure the maximum local bond strength, all bond tests were carried out on deformed reinforcing bars that did not yield as the embedded bond length was relatively short. Bond test results have been presented in two separate chapters in which 48 monotonic bond tests and 27 cyclic bond tests are presented. Permutations of the experiments include the loading rate, cyclic loading history, concrete strength (25 to 70 MPa), concrete age, cover thickness, bar diameter (16 and 20 mm), embedded length, and position of the embedded bond region within the specimen (close or far away to the free surface). The parametric study showed that the concrete strength significantly influences the maximum bond strength and that it is reasonable to normalise the bond stress by the square-root of the concrete compressive strength, √(f'c). The generalised monotonic bond behaviour is described within. An important outcome of the research is that the measured bond strength and stiffness was higher than stated by the bond stress-slip relationship in the fib Model Code 2010. To account for these observed differences, an alternative model is proposed for the local monotonic bond stress-slip relationship. Cyclic bond tests showed a significant proportion of the total bond degradation occurs after the loading cycle in the peak bond strength range, which is when bond slip has exceeded 0.5 mm. Subsequent loading to constant slip values showed a linear relationship between the amount of bond strength degradation and the log of the number of cycles that were applied. To a greater extent, the cyclic bond deterioration depends on the bond slip range, regardless of whether the applied load cycling is half- or fully-reversed. The observed bond deterioration and hysteretic energy dissipated during cyclic loading was found to agree reasonably well between these cyclic tests with different loading protocols. The cyclic bond deterioration was also found to be reasonably consistent exponential damage models found in the literature. This research concluded that the deformed reinforcing bars used in NZ construction, embedded in moderate to high strength concrete, are able to develop high local bond stresses that are mobilised by a small amount of local bond slip. Although the relative rib geometry was not varied within this experimental programme, a general conclusion of this thesis is that deformed bars currently available in NZ have a relative rib bearing area that is comparatively higher than the test bars used in previous international research. From the parametric study it was found that the maximum monotonic bond strength is significant enhanced by dynamic loading rates. Experimental evidence of high bond strength and initial bond stiffness generally suggests that only a small amount of local bond slip that can occur when the deformed test bar was subjected to large tension forces. Minimal bond slip and bond damage limits the effective yielding length that is available for the reinforcing steel to distribute inelastic material strains. Consequently, the potential for brittle fracture of the reinforcement may be a more problematic and widespread issue than is apparent to structural engineers. This research has provided information that improve the reliability of engineering predictions (with respect to ductility capacity) of maximum crack widths and the extent of bond deterioration that might occur in RC structures during seismic actions.

TVs, shopping trolleys, beds, mattresses, even a gun. That is just some of the rubbish found by residents surrounding Christchurch's residential red zone. The area used to be filled with houses, but damage after the Canterbury earthquakes forced thousands of homes to be demolished. While many of the old suburban roads remain, the area now resembles a park. But it is now attracting those wanting to dump their rubbish for free - and Land Information NZ, which controls the land, has removed 25 tonnes of trash since January. Residents have had enough as well - with some taking matters into their own hands. Checkpoint reporter Logan Church has the story.

Christchurch red zone residents say the area is experiencing an increasing amount of petty crime and dumped rubbish, due to a lack of people. The red zone was established after thousands of houses - and the land underneath them - suffered severe damage in the 2010 and 2011 earthquakes. Last year (2019), a Regeneration Plan for the area was signed off by the government - which included building walkways, cycleways, forests, wetlands, and sport and recreation areas. That's all designed to get people back into the red zone area - but much of the work is still years away. Logan Church met a resident who told him that in the meantime, things are deteriorating.

David says, "This thesis is concerned with setting up the first computer-controlled laser Raman spectroscopy equipment (shown in one photo - that's me wearing the laser safety goggles) in New Zealand and using it to measure the vibrational spectrum of novel materials grown in the Physics Department. It is very likely that my setup was also the first in the Southern Hemisphere".

Many areas of Christchurch are underwater, dealing with what's been described as the worst flooding since the earthquakes. The high tide has just passed, with the rivers already running across roads and flooding into some homes. Schools have been closed, businesses inundated and dozens of roads around the city, closed. Already more than 70mm of rain has fallen in the past 24 hours, making it the city's wettest July on record. Now as the bad weather moves south the army has been put on standby in Dunedin for the expected deluge there. RNZ reporters Niva Chittock, Adam Burns and cameraman Nathan McKinnon are in Christchurch with the details.

Gulls are well known for swooping in and flogging food off your plate or picnic and now they are making a complete menace of themselves in Christchurch's New Regent street. Local businesses are being over-run by the red and black-billed gulls that are nesting on the rooves of buildings along the street, swooping and pooping all over the place. It's not the first time they've invaded, they started breeding in 2019 in an earthquake damaged building on the corner of Armagh and New Regent streets. The problem is both the red and black-billed gulls are protected. Casey Alderson from Belle Cafe spoke to Lisa Owen.

A video of an interview with Tony Simpson, Principal of Phillipstown School, about the High Court's ruling on the merger of Woolston School and Phillipstown School. The Ministry of Education planned to merge the schools after the 22 February 2011 earthquake. However, Justice John Fogarty declared that the Ministry's consultation process failed to meet the requirements of the Education Act in two respects and that the merger was unlawful. Simpson talks about the joy he felt on hearing the news, his disappointment that it came down to a High Court decision, and his plans for the school's future.
