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.

Three excavators sit on top of the demolition rubble where the Crowne Plaza Hotel once stood. In the background are the Forsyth Barr building (left), the Victoria Apartments (centre), and the Environment Court building (right).
A brick building supported by shipping containers on Colombo Street. The side wall of the building has been revealed by the demolition of the adjoining building. Security fences have been placed around the building to restrict access.
Santarium is cutting 36 jobs in Christchurch as it pulls out of manufacturing Weetbix in the city. The final engineering report on the site says the factory's tower block is an earthquake risk, and demolition starts tomorrow.
A person takes a photograph during the Rally for the Cathedral in Cranmer Square. He is wearing a mask identified with the "Anonymous" movement. The rally protested the proposed demolition of the ChristChurch Cathedral.
Damage to a building on Colombo Street. Beside it is a sign that says 'Footpath closed Please use alternative route'. Ongoing demolition work and street cordons in Christchurch mean that gardens are left and becoming overgrown.
Two excavators and building rubble in front of the Terrace on the Park apartment complex. Two buildings in the complex required urgent demolition, and the other buildings in the complex will eventually be demolished.

Flowers blooming in a vacant site left by the demolition of a building at the corner of Worcester Street and Stanmore Road. On the wall at the back are the words 'Do Not Demo!!'.
Looking down Victoria Street, demolition site on the right and the Crowne Plaza Hotel at the end of the street. Flags in Canterbury colours, red and black can be seen on the street lights.

Cunningham House at the Christchurch Botanic Gardens is still closed due to earthquake damage. I wonder if it will ever re-open or suffer the demolition fate many other iconic structures in Christchurch have.

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".

Looking down Gloucester Street where ongoing demolition and reconstuction work are continuing. Street signs on the road say 'no road marking' and 'truck crossing'. In the background is a Wilson's carpark, converted from a site where a building has been demolished.
