A corner of the Cranmer Courts on Montreal Street. The masonry has collapsed onto the footpath, bringing steel and wooden bracing with it.
Steel girders supporting the Colombo Street overbridge. Cracks in one of the concrete pillars run through a graffiti paste-up of a woman.
The ruins of the historic Durham Street Methodist Church in the aftermath of the 22 February 2011 earthquake. The only parts of the building still upright are those supported by steel braces placed there after the 4 September 2010 earthquake to strengthen the building as it awaited repairs. Rubble has spilled out onto the street, knocking over the safety fences that were also erected after September. Silt from liquefaction has covered the road around the church.

A photograph of the earthquake-damaged Our City O-Tautahi Building on the corner of Worcester Street and Oxford Terrace. Steel bracing has been placed against the building to secure the brick walls. The bracing is supported by large concrete blocks. Wire fences have also been placed around the bottom of the building as a cordon. Scaffolding has been erected around the tower to the right.
A photograph of the earthquake damage to the Carlton Hotel on the corner of Papanui Road and Bealey Avenue. The wall of the top storey of the building has crumbled, and bricks have fallen onto the footpath. Wire fencing, road cones, and cordon tape have been placed around the building as a cordon. Scaffolding and steel bracing can be seen against the front of the building.

This paper presents preliminary field observations on the performance of selected steel structures in Christchurch during the earthquake series of 2010 to 2011. This comprises 6 damaging earthquakes, on 4 September and 26 December 2010, February 22, June 6 and two on June 13, 2011. Most notable of these was the 4 September event, at Ms7.1 and MM7 (MM as observed in the Christchurch CBD) and most intense was the 22 February event at Ms6.3 and MM9-10 within the CBD. Focus is on performance of concentrically braced frames, eccentrically braced frames, moment resisting frames and industrial storage racks. With a few notable exceptions, steel structures performed well during this earthquake series, to the extent that inelastic deformations were less than what would have been expected given the severity of the recorded strong motions. Some hypotheses are formulated to explain this satisfactory performance. http://db.nzsee.org.nz/SpecialIssue/44%284%290297.pdf
