The damaged Knox Presbyterian Church on the corner of Victoria Street and Bealey Avenue. The brickwork in the gables of the building has crumbled onto the footpath below, exposing the wooden structure beneath and the inside of the church.

Damage to the north-west corner of the Cathedral of the Blessed Sacrament. The upper part of the corner structure has collapsed. A statue of the Virgin Mary can be seen in a window. The photographer comments, "A bike ride around the CBD. Catholic Cathedral, Barbadoes St".

A photograph of the Canterbury Provincial Chambers on Durham Street. The building has been cordoned off with wire fencing and the roof covered by plastic sheeting. Much of the masonry has been removed and a wooden structure constructed inside. A crane can be seen behind.

A photograph of the Arts Centre taken from Rolleston Avenue near the Botanic Gardens. The building has been cordoned off by wire fencing and a wooden structure has been secured to the tower with tie-downs to help reduce damage from further aftershocks.

Buildings subject to earthquake shaking will tend to move not only horizontally but also rotate in plan. In-plan rotation is known as “building torsion” and it may occur for a variety of reasons, including stiffness and strength eccentricity and/or torsional effects from ground motions. Methods to consider torsion in structural design standards generally involve analysis of the structure in its elastic state. This is despite the fact that the structural elements can yield, thereby significantly altering the building response and the structural element demands. If demands become too large, the structure may collapse. While a number of studies have been conducted into the behavior of structures considering inelastic building torsion, there appears to be no consensus that one method is better than another and as a result, provisions within current design standards have not adopted recent proposals in the literature. However, the Canterbury Earthquakes Royal Commission recently made the recommendation that provisions to account for inelastic torsional response of buildings be introduced within New Zealand building standards. Consequently, this study examines how and to what extent the torsional response due to system eccentricity may affect the seismic performance of a building and considers what a simple design method should account for. It is concluded that new methods should be simple, be applicable to both the elastic and inelastic range of response, consider bidirectional excitation and include guidance for multi-story systems.

Damage to the front of the Cathedral of the Blessed Sacrament. The upper part of the corner structures have collapsed, and the cross on the roof is on a lean. A statue of the Virgin Mary can be seen in a window. The photographer comments, "A bike ride around the CBD. Catholic Cathedral, Barbadoes St".

A photograph of the earthquake damage to a building on Armagh Street. The walls of the building have crumbled and the bricks have spilt onto the footpath, exposing the wooden structure beneath. Police tape and road cones have been placed around the building as a cordon.
