one of Christchurch's abandoned suburbs. The land moved - bricks and block walls everywhere collapsed - two multi story buildings folded - 184 people died. Wooden framed houses largely stayed up, many concrete slabs cracked, power poles leaned in liquid ground, surface bubbled, services ruptured .... damage to the cbd still gets the most cover...

A information board on the fence around the Homestead at Mona Vale. It says 'This hertiage building is managed by the Christchurch City Council on behalf of the city's residents. Until recently it served as a restaurant and function centre. This building was damaged in the 2010/2011 Canterbury earthquakes and ongoing aftershocks. Propping walls and other support is designed to keep the building weather-proof until a decision about its future can be made'.

A photograph of the north side of the ChristChurch Cathedral in Cathedral Square. The front of the building has been propped up with steel bracing but further earthquakes have caused more damage, leaving a gap between the bracing and the wall. The tower has been partially demolished, but the lower section is still visible. Wire fencing has been placed around the entire building. In the background, a crane is rising high above the square.

Drywalls are the typical infill or partitions used in new structures. They are usually located within structural frames and/or between upper and lower floor slabs in buildings. Due to the materials used in their construction, unlike masonry blocks, they can be considered as light non-structural infill/partition walls. These types of walls are especially popular in New Zealand and the USA. In spite of their popularity, little is known about their in-plane cyclic behaviour when infilled within a structural frame. The cause of this lack of knowledge can be attributed to the typical assumption that they are weak non-structural elements and are not expected to interact with the surrounding structural system significantly. However, recent earthquakes have repeatedly shown that drywalls interact with the structure and suffer severe damage at very low drift levels. In this paper, experimental test results of two typical drywall types (steel and timber framed) are reported in order to gather further information on; i) their reverse cyclic behaviour, ii) inter-storey drift levels at which they suffer different levels of damage, iii) the level of interaction with the surrounding structural frame system. The drywall specimens were tested using quasi-static reverse cyclic testing protocols within a full scale precast RC frame at the Structures Laboratory of the University of Canterbury.
