Cracks in the concrete structure of the Lichfield Street car parking building.
A photograph of the earthquake damage to a building on Oxford Terrace. The wall to the right has collapsed, the concrete blocks spilling onto the footpath in front. USAR codes have been spray-painted on the ground at the entrance of the building.

A photograph of the earthquake damage to a block of buildings in central Christchurch. The basement of the buildings have collapsed and the concrete blocks have spilled into the car park. Large cracks have also formed in between the blocks in the walls of the building to the left.
A photograph of the earthquake damage to a stairwell in the Crowne Plaza Hotel on the corner of Kilmore and Durham Streets. Large sections of the concrete wall behind the stair rail have broken away to reveal the steel reinforcement underneath.

The Christchurch region of New Zealand experienced a series of major earthquakes and aftershocks between September 2010 and June 2011 which caused severe damage to the city’s infrastructure. The performance of tilt-up precast concrete buildings was investigated and initial observations are presented here. In general, tilt-up buildings performed well during all three major earthquakes, with mostly only minor, repairable damage occurring. For the in-plane loading direction, both loadbearing and cladding panels behaved exceptionally well, with no significant damage or failure observed in panels and their connections. A limited number of connection failures occurred due to large out-of-plane panel inertia forces. In several buildings, the connections between the panel and the internal structural frame appeared to be the weakest link, lacking in both strength and ductility. This weakness in the out-of-plane load path should be prevented in future designs.
