As seen from Hereford St over the demolition of the corner buildings.
Text at top left reads 'Don't forget rubbish day' The cartoon is a large wheelie bin stacked high with debris from 'old dunger buildings'. Someone in a damaged house nearby says 'Good riddance!' Context - Two earthquakes and hundreds of aftershocks have hit Christchurch, the first on 4 September 2010 and a second more devastating one on 22 February 2011. Earthquake Recovery Minister Gerry Brownlee may or may not have actually used the words 'old dungers' to describe some of Christchurch's heritage buildings that are not worth keeping but he might as well have done because many people believe that this is the way he thinks. Debate about which heritage buildings should be kept and which demolished has begun along with debate about how the city should be rebuilt. Quantity: 1 digital cartoon(s).
Heritage buildings are an important element of our urban environments, representing the hope and aspirations of a generation gone, reminding us of our achievements and our identity. When heritage buildings suffer damage, or fall into disrepair they are either met by one of two extremes; a bulldozer or painstaking repair. If the decision to conserve defeats the bulldozer, current heritage practice favours restoration into a mausoleum-type monument to yesteryear. But what if, rather than becoming a museum, these heritage buildings could live on and become a palimpsest of history? What if the damage was embraced and embodied in the repair? The Cathedral of the Blessed Sacrament on Barbadoes Street, Christchurch is the case study building for this thesis. Suffering damage in the Canterbury earthquakes of 2010 and 2011, the Cathedral sits in ruin waiting for decisions to be made around how it can be retained for future generations. This thesis will propose a reconstruction for the Cathedral through the analysis of precedent examples of reconstructing damaged heritage buildings and guided by a heritage framework proposed in this thesis. The employed process will be documented as an alternative method for reconstructing other damaged heritage buildings.
As a result of the Christchurch Earthquake that occurred on 22nd February 2011 and the resultant loss of life and widespread damage, a Royal Commission of Enquiry was convened in April 2011. The Royal Commission recommended a number of significant changes to the regulation of earthquake prone building in New Zealand. Earthquake prone buildings are buildings that are deemed to be of insufficient strength to perform adequately in a moderate earthquake. In response to the Royal Commission recommendations the New Zealand Government carried out a consultative process before announcing proposed changes to the building regulations in August 2013. One of the most significant changes is the imposition of mandatory strengthening requirements for earthquake prone buildings on a national basis. This will have a significant impact on the urban fabric of most New Zealand towns and cities. The type of traditional cost benefit study carried out to date fails to measure these impacts and this paper proposes an alternative methodology based on the analysis of land use data and rating valuations. This methodology was developed and applied to a small provincial town in the form of a case study. The results of this case study and the methodology used are discussed in this paper.
Reconnaissance reports have highlighted the poor performance of non-ductile reinforced concrete buildings during the 2010-11 Canterbury earthquakes. These buildings are widely expected to result in significant losses under future earthquakes due to their seismic vulnerability and prevalence in densely populated urban areas. Wellington, for example, contains more than 70 pre-1970s multi-storey reinforced concrete buildings, ranging in height from 5 to 18 storeys. This study seeks to characterise the seismic performance and evaluate the likely failure modes of a typical pre-1970s reinforced concrete building in Wellington, by conducting advanced numerical simulations to evaluate its 3D nonlinear dynamic response. A representative 9-storey office building constructed in 1951 is chosen for this study and modelled in the finite element analysis programme DIANA, using a previously developed and validated approach to predict the failure modes of doubly reinforced walls with confined boundary regions. The structure consists of long walls and robust framing elements resulting in a stiff lateral load resisting system. Barbell-shaped walls are flanked by stiff columns with sufficient transverse reinforcement to serve as boundary regions. Curved shell elements are used to model the walls and their boundary columns, for which the steel reinforcement is explicitly modelled. Line elements are used to model the frame elements. The steel reinforcement in each member is explicitly modelled. The floor slabs are modelled using elastic shell elements. The model is analysed under short and long duration ground motions selected to match site specific targets in Wellington at the DBE and MCE intensity levels. The observed response of the building including drift profiles at each intesity level, strain localization effects around wall openings, and the influence of bidirectional loading are discussed.

A photograph of the badly-damaged John Bull Cycles building on the corner of Colombo Street and Tuam Street. Most of the building's facade has fallen away and it has been cordoned off with wire fencing. Signs indicating that the business has relocated can be seen in the window.
A photograph of a trolley stacked with computers and keyboards in the Civil Suite at the University of Canterbury after the 4 September 2010 earthquake. The photograph was taken on the day when the staff were allowed to return to the building.
Damage to the British Hotel on Oxford Street. The top of the building has crumbled bringing the roof down with it. Bricks lay along the footpath where they landed. Wire fencing has used to create a cordon around the building.
Damage to a building on the corner of Manchester and Gloucester Streets. The facade of the top storey has crumbled, the bricks falling into the street. Rubble from damaged buildings can be seen along the street in the distance.

A photograph of St Elmo Courts on the corner of Hereford and Montreal Streets. Cracks can be seen between the windows of the building and wire fencing has been placed around the bottom as a cordon. Two workers in hard hats in visibility vests are examining the building from street level.

The remains of Simply Catering Cafe on the corner of Salisbury and Madras Streets, which have been cordoned off by a safety fence. The business' owners have spray painted on the back wall of the building, "We'll be back". Behind the building an orange tarpaulin can be seen draped over a roof.
The front wall of St John the Baptist Church in Latimer Square. Plywood and tarpaulins have been used to weather proof the gaps where masonry has fallen away from the building. Some of the fallen masonry is stacked on a pallet at the base of the building.
