During the 2010/2011 Canterbury earthquakes, several reinforced concrete (RC) walls in multi-storey buildings formed a single crack in the plastic hinge region as opposed to distributed cracking. In several cases the crack width that was required to accommodate the inelastic displacement of the building resulted in fracture of the vertical reinforcing steel. This type of failure is characteristic of RC members with low reinforcement contents, where the area of reinforcing steel is insufficient to develop the tension force required to form secondary cracks in the surrounding concrete. The minimum vertical reinforcement in RC walls was increased in NZS 3101:2006 with the equation for the minimum vertical reinforcement in beams also adopted for walls, despite differences in reinforcement arrangement and loading. A series of moment-curvature analyses were conducted for an example RC wall based on the Gallery Apartments building in Christchurch. The analysis results indicated that even when the NZS 3101:2006 minimum vertical reinforcement limit was satisfied for a known concrete strength, the wall was still susceptible to sudden failure unless a significant axial load was applied. Additionally, current equations for minimum reinforcement based on a sectional analysis approach do not adequately address the issues related to crack control and distribution of inelastic deformations in ductile walls.

The coroner has ruled the search and rescue effort at Christchurch's CTV building did not contribute to the deaths of eight people who survived the initial collapse. However Gordon Matenga criticised nearly every aspect of the fire service's response to the tragedy that claimed 115 of the 185 lives lost in the February 2011 earthquake.

A photograph of an Urban Search and Rescue team member examining the contents of a flat on Poplar Street during the Residential Access Project. The project gave residents temporary access within the red-zone cordon in order to retrieve items from their homes. The buildings wall has crumbled leaving the room exposed.

A panoramic photograph taken at the front of Christ Church Cathedral. The front of the cathedral has steel bracing against it to limit further damage. The upper part of the front wall has crumbled completely, exposing the inside space. The Chalice sculpture is to the right and the BNZ building can be seen in the background.

A sign outside the Croydon House Bed and Breakfast Hotel on Armagh Street reading, "Don't touch this lady without owner's permission". The east side of the building has collapsed, the bricks falling into the neighbouring property. Tape reading, "Restricted area, please keep out" has been placed around the property.

Photograph captioned by BeckerFraserPhotos, "The All Saints Church in Sumner. The traditional building materials and style of this church makes it look older than 1963. At the moment it is hidden behind a long line of containers protecting the road from potential rock fall hazards".

An excavator bunching up scrap metal as part of efforts to clear the site of the demolished Hillary and Marshall Limited building on Manchester Street. A pile of scrapped wooden components can be seen at the back of the site, and a pile of masonry is visible in the foreground.

The fish and chip shop on Hills Road in Edgeware. The building is red stickered meaning it is unsafe to enter. Without the glass in the window, the inside of the store is easy to see. Panelling on the walls and roof have come down and much of the furniture has been removed.

Topics - The Earthquake Recovery Minister, Gerry Brownlee, says it is important to be realistic about the demolition of Christchurch's heritage buildings following the powerful earthquake there last month. Motorists should prepare themselves for more increases in the price of petrol which, the AA warns, is likely to reach a new high.

A photograph submitted by Raymond Morris to the QuakeStories website. The description reads, "The Provincial Hotel, corner Barbadoes and Cashel streets is one the buildings now missing after the 2011 earthquakes, paintings of others can be found on the artist Raymond Morris’s flickr site (http://www.flickr.com/photos/rayso180/sets/72157626939956494/)".

Puari is a longstanding fishing area for Ngāi Tūāhuriri. It was claimed by chief Pita Te Hori for the hapū in 1868 but denied by the Crown, because the land had been allocated to settlers. This site is now owned by Ngāi Tahu and a building named after Te Hori stands here.

The Harbourlight Theatre on London Street in Lyttelton. There is cracking along the side of the building and damage to the domes on top of the towers. Bracing has been placed at the top to limit further damage and to stop debris from falling on the road.
