A photograph of the earthquake-damaged Cathedral of the Blessed Sacrament on Barbadoes Street. Rubble from the collapsed tower is lying on the ground in front. A car has been crushed under this rubble. Wire fencing, shipping containers, and road cones have been placed around the building as a cordon.

A photograph of the earthquake damage to the Christchurch Chinese Methodist Church on Papanui Road. The gable walls have crumbled, bricks spilling onto the ground. The tower has been removed and braced on the ground in front. Cordon fencing has been placed around the building. Parts of the fence have been decorated with hearts and the word 'love'.

A photograph of a detail of Mike Hewson's installation 'View from the Studio' in Re:Start Mall. An outline of the cathedral's tower is sketched on plywood, accompanied by the words, "Mike Hewson 2012. 'View From Studio'. (We should try keep some part of the cathedral rather than just demo-ing it)".

A photograph looking south down Colombo Street from the intersection of Gloucester Street. In the distance a crane is hanging over Cathedral Square. Below the crane is a pile of rubble from the partially-demolished tower of ChristChurch Cathedral. To the right is a smaller crane and a steel structure which will be used to brace the front of the Cathedral.

The northern side of the Christ Church Cathedral with the cafe and store in the foreground. Shipping containers have been placed around the eastern side of the Cathedral to protect the road from falling debris. Wire fencing has also been placed around the building as a cordon. To the right, the damaged and party deconstructed tower can be seen with the missing spire which fell during the 22 February 2011 earthquake.

A photograph of members of the Clandeboye Emergency Response Team and the Red Cross Team working on High Street near the intersection with Manchester Street. In the background is a large pile of rubble from the ANZ Bank building. In the foreground the members have placed their bags on a group of outdoor chairs and tables still on the footpath.

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.

The Arts Centre photographed shortly after the 22 February 2011 earthquake. A large crack can be seen in the tower and part of the brickwork around the clock has collapsed onto the pavement below. Scaffolding was placed up against the building after the 4 September 2010 earthquake and the gable was braced with wooden planks. This probably limited the damage to this part of the building. The building has been cordoned off with tape reading, 'Danger keep out'. A sign in front of the door reads, 'Site closed'.

Townsend Telescope Pre-Earthquake Photographs 02

A photograph of the Townsend Telescope in the Observatory at the Christchurch Arts Centre. In the bottom right-hand corner of the photograph is a pulley for the telescope's clock drive. This is one of the pieces that went missing when the Observatory tower collapsed in the 22 February 2011 earthquake. This image was used by Graeme Kershaw, Technician at the University of Canterbury Department of Physics and Astronomy, to identify the telescope's parts after the 22 February 2011 earthquake.

An aerial photograph of the Christchurch CBD. The photograph has been captioned by BeckerFraserPhotos, "This photograph shows the many tall CBD buildings, with the Hotel Grand Chancellor under demolition in the centre of the photograph. The street in the foreground running up the photograph from left to right is Lichfield Street with the old Bus Exchange clearly visible".

Hereford Street can be seen in the foreground, as well as Worcester Street running towards the the Christ Church Cathedral. The empty site of the Press Building and Warners hotel can also be seen".

Testing of Reinforced Concrete Frames Extracted from a Building Damaged du…

Research papers, The University of Auckland Library

In the aftermath of the 2010-2011 Canterbury earthquakes in New Zealand, the residual capacity and reparability of damaged reinforced concrete (RC) structures was an issue pertinent to building owners, insurers, and structural engineers. Three precast RC moment-resisting frame specimens were extracted during the demolition of the Clarendon Tower in Christchurch after sustaining earthquake damage. These specimens were subjected to quasi-static cyclic testing as part of a research program to determine the reparability of the building. It was concluded that the precast RC frames were able to be repaired and retrofitted to an enhanced strength capacity with no observed reduction in displacement capacity, although the frames with “shear-ductile” detailing exhibited less displacement ductility capacity and energy dissipation capacity than the more conventionally detailed RC frames. Furthermore, the cyclic test results from the earthquake-damaged RC frames were used to verify the predicted inelastic demands applied to the specimens during the 2010-2011 Canterbury earthquakes. https://www.concrete.org/publications/acistructuraljournal.aspx
