Graffiti on a wooden wall depicts a child pointing at a site across the street and reads "I remember when the Kazbah was over there." The photographer comments, "A local street artist has commemorated Christchurch's deadliest earthquake. The anniversary is tomorrow. Where the photograph was taken was the site of the Ozone Hotel, which has now gone as well. For some of us who live and work in the East of Christchurch the earthquake was not what happened in the City as we were almost unaware of it. We had no water, toilets and most of all no electricity for weeks. For myself petrol was low and with tales of all the petrol stations on our side of town being damaged we could not take the chance of venturing out on severely damaged roads to find no petrol and the possibility of not getting home. We walked around and saw the damage that was local to us. TJ's Kazbah was one that stood out. A building that had a beauty with its round tower standing proud and always looked well kept - it was now collapsed. Its tower, which was once pointing towards the sky was laying on its side. It had kept its shape, but had a lightning shaped crack through it. The one thing that kept us feeling almost normal through the coming weeks was The Press our daily paper still being delivered even though the Press building and staff had suffered so badly themselves.
Very little research exists on total house seismic performance. This testing programme provides stiffness and response data for five houses of varying ages including contributions of non-structural elements. These light timber framed houses in Christchurch, New Zealand had minor earthquake damage from the 2011 earthquakes and were lateral load tested on site to determine their strength and stiffness, and preliminary damage thresholds. Dynamic characteristics were also investigated. Various loading schemes were utilised including quasi-static loading above the foundation, unidirectional loading through the floor diaphragm, cyclic quasi-static loading and snapback tests. Dynamic analysis on two houses provided the seismic safety levels of post-quake houses with respect to local hazard levels. Compared with New Zealand Building Standards all the tested houses had an excess of strength, damage is a significant consideration in earthquake resilience and was observed in all of the houses. A full size house laboratory test is proposed.
The former Ozone Dressing Sheds in North New Brighton, with broken and boarded-up windows. The photographer comments, "This is the Ozone as it was before it was demolished. It appeared to have been in the process of being redecorated internally, but the February Christchurch earthquake seems to have caused its demise".
A copy of a letter from Hugo Kristinsson which was sent to Roger Sutton on 19 September 2013. The letter was sent on behalf of Empowered Christchurch. In the letter, Kristinsson expresses his concern about changes to the Building Act which he states, 'waive liability for the Building Consent Authority when repairs are carried out on homes with land damage'. He also discusses the CERA community forums, which he feel are not fufilling their purpose of supporting and informing the Canterbury community. Lastly, Kristinsson lodges an Official Information Act request, asking for all forum notices and minutes to be released to the public and for access to land information to be provided.
People walk down Colombo Street past collapsed buildings shortly after the 22 February earthquake. The photographer comments, "Just after the aftershock settled on Tuesday afternoon, myself and colleagues fled our Tuam Street office to absolute devastation outside. We couldn't see more than a block in either direction due to the clouds of dust that had arisen from buildings that had just collapsed ... From here, we picked up our vehicles from the CCC car park and headed out to get out of the chaos to a position where we could check on loved ones. Heading first along Manchester Street, buildings that were already heavily damaged were now completely written off. We couldn't get much further down Manchester Street so eventually made it to Colombo Street".

This thesis describes the strategies for earthquake strengthening vintage clay bricks unreinforced masonry (URM) buildings. URM buildings are well known to be vulnerable to damage from earthquake-induced lateral forces that may result in partial or full building collapse. The 2010/2011 Canterbury earthquakes are the most recent destructive natural disaster that resulted in the deaths of 185 people. The earthquake events had drawn people’s attention when URM failure and collapse caused about 39 of the fatality. Despite the poor performance of URM buildings during the 2010/2011 Canterbury earthquakes, a number of successful case study buildings were identified and their details research in-depth. In order to discover the successful seismic retrofitting techniques, two case studies of retrofitted historical buildings located in Christchurch, New Zealand i.e. Orion’s URM substations and an iconic Heritage Hotel (aka Old Government Building) was conducted by investigating and evaluating the earthquake performance of the seismic retrofitting technique applied on the buildings prior to the 2010/2011 Canterbury earthquakes and their performance after the earthquakes sequence. The second part of the research reported in this thesis was directed with the primary aim of developing a cost-effective seismic retrofitting technique with minimal interference to the vintage clay-bricks URM buildings. Two retrofitting techniques, (i) near-surface mounted steel wire rope (NSM-SWR) with further investigation on URM wallettes to get deeper understanding the URM in-plane behaviour, and (ii) FRP anchor are reported in this research thesis.
Earthquakes cause significant damage to buildings due to strong vibration of the ground. Levitating houses using magnets and electromagnets would provide a complete isolation of ground motion for protecting buildings from seismic damage. Two types of initial configuration for the electromagnet system were proposed with the same air gap (10mm) between the electromagnet and reluctance plate. Both active and passive controller are modelled to investigate the feasibility of using a vibration control system for stabilizing the magnetic system within the designed air gap (10mm) in the vertical direction. A nonlinear model for the magnetic system is derived to implement numerical simulation of structural response under the earthquake record in Christchurch Botanic Gardens on 21 February 2011. The performance of the uncontrolled and the controlled systems are compared and the optimal combination of control gains are determined for the PID active controller. Simulation results show both active PID controller with constant and nonlinear attracting force are able to provide an effective displacement control within the required air gap (+/-5mm). The maximum control force demand for the PID controller in the presence of nonlinear attracting force is 4.1kN, while the attracting force in equilibrium position is 10kN provided by the electromagnet. These results show the feasibility of levitating a house using the current electromagnet and PID controller. Finally, initial results of passive control using two permanent magnets or dampers show the structural responses can be effectively reduced and centralized to +/-1mm using a nonlinear centring barrier function.
This is an interim report from the research study performed within the NHRP Research Project “Impacts of soil liquefaction on land, buildings and buried pipe networks: geotechnical evaluation and design, Project 3: Seismic assessment and design of pipe networks in liquefiable soils”. The work presented herein is a continuation of the comprehensive study on the impacts of Christchurch earthquakes on the buried pipe networks presented in Cubrinovski et al. (2011). This report summarises the performance of Christchurch City’s potable water, waste water and road networks through the 2010-2011 Canterbury Earthquake Sequence (CES), and particularly focuses on the potable water network. It combines evidence based on comprehensive and well-documented data on the damage to the water network, detailed observations and interpretation of liquefaction-induced land damage, records and interpretations of ground motion characteristics induced by the Canterbury earthquakes, for a network analysis and pipeline performance evaluation using a GIS platform. The study addresses a range of issues relevant in the assessment of buried networks in areas affected by strong earthquakes and soil liquefaction. It discusses performance of different pipe materials (modern flexible pipelines and older brittle pipelines) including effects of pipe diameters, fittings and pipeline components/details, trench backfill characteristics, and severity of liquefaction. Detailed breakdown of key factors contributing to the damage to buried pipes is given with reference to the above and other relevant parameters. Particular attention is given to the interpretation, analysis and modelling of liquefaction effects on the damage and performance of the buried pipe networks. Clear link between liquefaction severity and damage rate for the pipeline has been observed with an increasing damage rate seen with increasing liquefaction severity. The approach taken here was to correlate the pipeline damage to LRI (Liquefaction Resistance Index, newly developed parameter in Cubrinovski et al., 2011) which represents a direct measure for the soil resistance to liquefaction while accounting for the seismic demand through PGA. Key quality of the adopted approach is that it provides a general methodology that in conjunction with conventional methods for liquefaction evaluation can be applied elsewhere in New Zealand and internationally. Preliminary correlations between pipeline damage (breaks km-1), liquefaction resistance (LRI) and seismic demand (PGA) have been developed for AC pipes, as an example. Such correlations can be directly used in the design and assessment of pipes in seismic areas both in liquefiable and non-liquefiable areas. Preliminary findings on the key factors for the damage to the potable water pipe network and established empirical correlations are presented including an overview of the damage to the waste water and road networks but with substantially less detail. A comprehensive summary of the damage data on the buried pipelines is given in a series of appendices.
The EQC (Earthquake Commission) has developed new standards and designs to help rebuild Christchurch after the earthquakes of 2010 and 2011. The Department of Building and Housing have produced some generic building foundation and floor designs that can be used for residential homes being built or repaired on liquefied, tilting, unsettled and/or damaged land.

The back of the old Odeon movie theatre, that was for about 15-20 years a New Life Christian Centre. This is earthquake damage, although the roof was lifted off in 2011. I don't know whether this is a building that they want to save or still awaiting demolition. The smaller building to the immediate left was restored a few years ago and for a...
