As a result of the Canterbury earthquakes, over 60% of the concrete buildings in the Christchurch Central Business District have been demolished. This experience has highlighted the need to provide guidance on the residual capacity and repairability of earthquake-damaged concrete buildings. Experience from 2010 Chile indicates that it is possible to repair severely damaged concrete elements (see photo at right), although limited testing has been performed on such repaired components. The first phase of this project is focused on the performance of two lightly-reinforced concrete walls that are being repaired and re-tested after damage sustained during previous testing.

A photograph of the earthquake damage to a house on Major Hornbrook Drive. The chimney has collapsed and many of the tiles have been lifted on the roof. Tarpaulins have been laid over the holes in the roof as waterproofing, but the closest has shredded. Gaps can be seen between the bricks in the wall and the wall to the left has crumbled.
