A photograph of a member of the Wellington Emergency Management Office Emergency Response Team standing in front of the earthquake-damaged Avonmore House on Hereford Street. Sections of the walls have crumbled, spilling bricks and masonry onto the footpath and street below. Many of the windows have warped, breaking the glass. USAR codes have been spray-painted on one of the columns. A red sticker taped to the door indicates that the building is unsafe to enter.

A photograph of emergency management personnel examining a block of earthquake-damaged rooms at Stonehurst Accommodation on Gloucester Street. The bottom storey of the block has collapsed and the remaining rooms are now resting on an incline. The front walls of these rooms have also collapsed and the rubble has spilled in to the courtyard in front. Cordon tape has been draped across the courtyard in front of the rubble. In the foreground there is liquefaction on the ground from a liquefaction volcano.

During the Christchurch earthquake of February 2011, several midrise buildings of Reinforced Concrete Masonry (RCM) construction achieved performance levels in the range of life safety to near collapse levels. These buildings were subjected to seismic demands higher than the building code requirements of the time and higher than the current New Zealand Loadings Standard (NZS-1170.5:2004). Structural damage to these buildings has been documented and is currently being studied to establish lessons to be learned from their performance and how to incorporate these lessons into future RCM design and construction practices. This paper presents a case study of a six story RCM building deemed to have reached the near collapse performance level. The RCM walls on the 2nd floor failed due to toe crushing reducing the building’s lateral resistance in the east-west direction. A nonlinear dynamic analysis on a 3D model was conducted to simulate the development of the governing failure mechanism. Preliminary analysis results show that the damaged walls were initially under large compression forces from gravity loads which caused increase in their lateral strength and reduced their ductility. After toe crushing failure developed, axial instability of the model was prevented by a redistribution of gravity loads.

Seismic retrofitting of unreinforced masonry buildings using posttensioning has been the topic of many recent experimental research projects. However, the performance of such retrofit designs in actual design level earthquakes has previously been poorly documented. In 1984 two stone masonry buildings within The Arts Centre of Christchurch received posttensioned seismic retrofits, which were subsequently subjected to design level seismic loads during the 2010/2011 Canterbury earthquake sequence. These 26 year old retrofits were part of a global scheme to strengthen and secure the historic building complex and were subject to considerable budgetary constraints. Given the limited resources available at the time of construction and the current degraded state of the steel posttension tendons, the posttensioned retrofits performed well in preventing major damage to the overall structure of the two buildings in the Canterbury earthquakes. When compared to other similar unretrofitted structures within The Arts Centre, it is demonstrated that the posttensioning significantly improved the in-plane and out-of-plane wall strength and the ability to limit residual wall displacements. The history of The Arts Centre buildings and the details of the Canterbury earthquakes is discussed, followed by examination of the performance of the posttension retrofits and the suitability of this technique for future retrofitting of other historic unreinforced masonry buildings. http://www.aees.org.au/downloads/conference-papers/2013-2/

The performance of retrofitted unreinforced masonry (URM) bearing wall buildings in Christchurch is examined, considering ground motion recordings from multiple events. Suggestions for how the experiences in Christchurch might be relevant to retrofit practices common to New Zealand, U.S. and Canada are also provided. Whilst the poor performance of unretrofitted URM buildings in earthquakes is well known, much less is known about how retrofitted URM buildings perform when subjected to strong ground shaking.

Members of the University of Canterbury's Digital Media Group in their temporary office in KB02 in Kirkwood Village, the complex of prefabs set up after the earthquakes to provide temporary office and classroom space for the university. The photographer comments, "The e-learning group and the video conferencing team are now located in the Kirkwood Village at the University of Canterbury. It's a very impressive project, about 60 buildings arranged in various configurations with some used for teaching or computer labs, and others as staff offices. We will probably stay here for several years now. Looking along the south wall, Herbert Thomas and Susan Tull already settled in and working".

Following the 2010–2011 Canterbury earthquakes, a renewed focus has been directed across New Zealand to the hazard posed by the country‘s earthquake-vulnerable buildings, namely unreinforced masonry (URM) and reinforced concrete (RC) buildings with potentially nonductile components that have historically performed poorly in large earthquakes. The research reported herein was pursued with the intention of addressing several recommendations made by the Canterbury Earthquakes Royal Commission of Inquiry which were classified into the following general categories:  Identification and provisional vulnerability assessment of URM and RC buildings and building components;  Testing, assessment, and retrofitting of URM walls loaded out-of-plane, with a particular focus on highly vulnerable URM cavity walls;  Testing and assessment of RC frame components, especially those with presumably non-ductile reinforcement detailing;  Portfolio management considering risks, regulations, and potential costs for a portfolio that includes several potentially earthquake-vulnerable buildings; and  Ongoing investigations and proposed research needs. While the findings from the reported research have implications for seismic assessments of buildings across New Zealand and elsewhere, an emphasis was placed on Auckland given this research program‘s partnership with the Auckland Council, the Auckland region accounting for about a third each of the country‘s population and economic production, and the number and variety of buildings within the Auckland building stock. An additional evaluation of a historic building stock was carried out for select buildings located in Hawke‘s Bay, and additional experimental testing was carried out for select buildings located in Hawke‘s Bay and Christchurch.

A photograph of a community member leading a group of children who are playing drums. On the wall behind the man there is a piece of traditional Pacific-island flax weaving. The photograph was taken at the Tiny Adventures launch at Niu Early Learning Centre in Linwood. Niu Early Learning Centre is managed by the Tongan Canterbury Community Trust. The Tiny Adventure card packs and smartphone app offer ideas, games and quick fun ways for parents to spend time with their children. They are a project of the All Right? mental health campaign.

Army personnel beside the damaged Colombo Street Wesleyan Church. Danger tape has been stretched across Colombo Street to create a cordon. The photographer comments, "After the 22nd February earthquake, my wife and I spent one night in a tent outside our home and then left to stay with friends in Timaru for a couple of nights. On the way along Brougham Street, we passed the Sydenham Church on the corner of Colombo Street and Brougham Street. As you can see from the photos, the upper area has been extensively damaged. Most of the damage appears to be on the east facing wall although we didn't get much of a look at the other sides or, of course, the interior".
