A digitally manipulated image of a mannequin. The photographer comments, "During the Christchurch earthquake on 22 February 2011 a lot of people were seriously injured or killed because they run out of buildings. Falling masonry from the exterior of the buildings hit them, but if they had remained inside they would have probably been perfectly safe".

A woman badly injured in the Christchurch earthquake is astonished a new building in the city has been found to have serious seismic flaws. The empty new office building at 230 High Street has multiple problems in its earthquake design that the city council was warned about almost two years ago. Construction of the seven-storey building continued even after those warnings in December 2017. Susie Ferguson speaks to University of Canterbury lecturer Ann Brower, who was crushed after falling masonry fell on her bus during the February twenty-second 2011 earthquake.

A view of the Cranmer Court building on the corner of Kilmore and Montreal Streets, showing damage from the 4 September 2010 earthquake. Masonry has fallen away from the apexes of several of the building's gables, which have been reinforced with timber bracing. A green cord has been used to tie bracing to the octagonal section on the corner of the building. This corner section is the part that housed Plato Creative from March 2008 to November 2009.

The Cranmer Court building, on the corner of Kilmore and Montreal Streets, after the 22 February 2011 earthquake. Large pieces of the building have collapsed, including the octagonal corner section that housed Plato Creative from March 2008 to November 2009. Masonry has fallen onto the footpath and road, and the site has been enclosed in a safety fence to keep people away. The whitewashed interior walls of one of the apartments can be seen.

Unreinforced masonry churches in New Zealand, similarly to everywhere else in the word have proven to be highly vulnerable to earthquakes, because of their particular construction features. The Canterbury (New Zealand) earthquake sequence, 2010-2011 caused an invaluable loss of local architectural heritage and of churches, as regrettably, some of them were demolished instead of being repaired. It is critical for New Zealand to advance the data collection, research and understanding pertaining to the seismic performance and protection of church buildings, with the aim to:

This paper describes the pounding damage sustained by buildings in the February 2011 Christchurch earthquake. Approximately 6% of buildings in Christchurch CBD were observed to have suffered some form of serious pounding damage. Typical and exceptional examples of building pounding damage are presented and discussed. Almost all building pounding damage occurred in unreinforced masonry buildings, highlighting their vulnerability to this phenomenon. Modern buildings were found to be vulnerable to pounding damage where overly stiff and strong ‘flashing’ components were installed in existing building separations. Soil variability is identified as a key aspect that amplifies the relative movement of buildings, and hence increases the likelihood of pounding damage. Building pounding damage is compared to the predicted critical pounding weaknesses that have been identified in previous analytical research.

This paper describes pounding damage sustained by buildings and bridges in the February 2011 Christchurch earthquake. Approximately 6% of buildings in Christchurch CBD were observed to have suffered some form of serious pounding damage. Almost all of this pounding damage occurred in masonry buildings, further highlighting their vulnerability to this phenomenon. Modern buildings were found to be vulnerable to pounding damage where overly stiff and strong ‘flashing’ components were installed in existing building separations. Soil variability is identified as a key aspect that amplifies the relative movement of buildings, and hence increases the likelihood of pounding damage. Pounding damage in bridges was found to be relatively minor and infrequent in the Christchurch earthquake.

Damaged buildings on Manchester Street, seen from the Tuam Street intersection. Police emergency tape cordons off the street. The photographer comments, "This was taken shortly after the 4th September earthquake. Police allowed us free access past the cordon and simply advised us to watch out for falling masonry. The access situation was much different after the February aftershock".

Existing unreinforced masonry (URM) buildings are often composed of traditional construction techniques, with poor connections between walls and diaphragms that results in poor performance when subjected to seismic actions. In these cases the application of the common equivalent static procedure is not applicable because it is not possible to assure “box like” behaviour of the structure. In such conditions the ultimate strength of the structure relies on the behaviour of the macro-elements that compose the deformation mechanisms of the whole structure. These macroelements are a single or combination of structural elements of the structure which are bonded one to each other. The Canterbury earthquake sequence was taken as a reference to estimate the most commonly occurring collapse mechanisms found in New Zealand URM buildings in order to define the most appropriate macroelements.

On 31 May, Dr Ann Brower will deliver a lecture at the University of Canterbury, titled: A Little Guy's Guide to Making a Difference after receiving the Critic and Conscience of Society Award earlier this month. Dr Brower is probably best known for her advocacy for more stringent regulation of earthquake-prone buildings, a campaign informed by her experience of being on a bus crushed by falling masonry in Christchurch's 2011 earthquake. Twelve passengers died on or beside the bus. She's also been prominent in highlighting high country land being transferred from Crown to private ownership.
