A digitally manipulated image of an excavator. The photographer comments, "This is a huge excavator in the Christchurch CBD. It is being used to clear away the enormous amount of rubble from the buildings being demolished. It seems that nearly all the big machinery from all other the world has been needed in the clean up of the earthquake damaged buildings and utilities".

Photograph captioned by BeckerFraserPhotos, "The machinery used in the demolitions keeps getting more sophisticated as the taller buildings are dealt with. This is the large crane put in place to work on the deconstruction and demolition of the BNZ Building".

A digitally manipulated image of an excavator demolishing a house. The photographer comments, "My neighbour I thought was going to be one of the first to be rebuilt in the area after being damaged in the 22 February 2011 earthquake, but the builders have knocked it down and not returned yet".

A digitally manipulated image of furniture and machinery. The photographer comments, "This furniture restoration company got caught in the middle of the Christchurch earthquake and lost a whole wall. After constant exposure to the elements everything now needs a bit of restoration. They are now working in a different part of Christchurch, but their past can still be seen".

Test results are presented for wall-diaphragm plate anchor connections that were axially loaded to rupture. These connection samples were extracted post-earthquake by sorting through the demolition debris from unreinforced masonry (URM) buildings damaged in the Christchurch earthquakes. Unfortunately the number of samples available for testing was small due to the difficulties associated with sample collection in an environment of continuing aftershocks and extensive demolition activity, when personal safety combined with commercial activity involving large demolition machinery were imperatives that inhibited more extensive sample collection for research purposes. Nevertheless, the presented data is expected to be of assistance to structural engineers undertaking seismic assessment of URM buildings that have existing wall-diaphragm anchor plate connections installed, where it may be necessary to estimate the capacity of the existing connection as an important parameter linked with determining the current seismic capacity of the building and therefore influencing the decision regarding whether supplementary connections should be installed.
