Following the magnitude 6.3 aftershock in Christchurch, New Zealand, on 22 February 2011, a number of researchers were sent to Christchurch as part of the New Zealand Natural Hazard Research Platform funded “Project Masonry” Recovery Project. Their goal was to document and interpret the damage to the masonry buildings and churches in the region. Approximately 650 unreinforced and retrofitted clay brick masonry buildings in the Christchurch area were surveyed for commonly occurring failure patterns and collapse mechanisms. The entire building stock of Christchurch, and in particular the unreinforced masonry building stock, is similar to that in the rest of New Zealand, Australia, and abroad, so the observations made here are relevant for the entire world.

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.

A video of a press conference with Canterbury Earthquake Recovery Minister Gerry Brownlee. Brownlee announced that cabinet has agreed to redevelop the hospital sites throughout Canterbury. This will include the building of additional operating theatres, the replacement of around 5000 beds, the expansion of the intensive care unit and emergency department, and the building of a new hospital for older persons in Burwood.

A video of a press conference about the ChristChurch Cathedral. The video includes statements by Jim Anderton and Stefano Pampanin, Associate Professor of Engineering at the University of Canterbury. Anderton and Pampanin discuss a report produced by the Great Christchurch Buildings Trust (GCBT) which outlines how the cathedral could be safely restored. The Anglican Church has agreed to review the report.

A digitally manipulated image of a direction signpost, with every sign pointing to parking. The photographer comments, "With around 70% of the buildings to be demolished in the CBD, Christchurch, New Zealand will be the biggest parking lot in the world for a few years".

This paper discusses the seismic performance of the standard RC office building in Christchurch that is given as a structural design example in NZS3101, the concrete structures seismic standard in New Zealand. Firstly the push-over analysis was carried out to evaluate the lateral load carrying capacity of the RC building and then to compare that carrying capacity with the Japanese standard law. The estimated figures showed that the carrying capacity of the New Zealand standard RC office building of NZS3101:2006 was about one third of Japanese demanded carrying capacity. Secondly, time history analysis of the multi-mass system was performed to estimate the maximum response story drift angle using recorded ground motions. Finally, a three-dimensional analysis was carried out to estimate the response of the building to the 22nd February, 2011 Canterbury earthquake. The following outcomes were obtained. 1) The fundamental period of the example RC building is more than twice that of Japanese simplified calculation, 2) The example building’s maximum storey drift angle reached 2.5% under the recorded ground motions. The main purpose of this work is to provide background information of seismic design practice for the reconstruction of Christchurch.
