A poster created by Empowered Christchurch to advertise their submission to the CERA Draft Transition Recovery Plan on social media.The poster reads, "Submission, CERA Draft Transition Recovery Plan. Seismic Risk. One thing we can learn from the past is that seismic risk in Canterbury has been underestimated before the earthquakes struck. This is confirmed in a report for EQC in 1991 (paper 2005). It is also the conclusion of the Royal Commission in the CTV report. A number of recommendations have been made but not followed. For example, neither the AS/NZS 1170.5 standard nor the New Zealand Geotechnical Society guidelines have been updated. Yet another recovery instrument is the Earthquake Prone Building Act, which is still to be passed by Parliament. As the emergency response part of the recovery is now behind us, we need to ensure sustainability for what lies ahead. We need a city that is driven by the people that live in it, and enabled by a bureaucracy that accepts and mitigates risks, rather than transferring them to the most vulnerable residents."

A photograph of street art on the wall of a building on Colombo Street. The artwork is by Otis Frizzell and depicts police officer Constable Nao Yoshimizu comforting the grieving relative of an earthquake victim. Constable Yoshimizu acted as liaison officer for the families of Japanese victims of the earthquake. The mural was commissioned by the New Zealand Police as a recruitment advertisement.

A photograph of Wharetiki on Colombo Street. A temporary fence made out of wooden slats, plastic netting, and safety tape has been constructed in front of the property. USAR codes have been spray-painted on one of the front windows and a red sticker has been placed on the front door. The red sticker indicates that the building is unsafe to enter.

Reinforced concrete buildings that satisfied modern seismic design criteria generally behaved as expected during the recent Canterbury and Kaikoura earthquakes in New Zealand, forming plastic hinges in intended locations. While this meant that life-safety performance objectives were met, widespread demolition and heavy economic losses took place in the aftermath of the earthquakes.The Christchurch central business district was particularly hard hit, with over 60% of the multistorey reinforced concrete buildings being demolished. A lack of knowledge on the post-earthquake residual capacity of reinforced concrete buildings was a contributing factor to the mass demolition.Many aspects related to the assessment of earthquake-damaged reinforced concrete buildings require further research. This thesis focusses on improving the state of knowledge on the post earthquakeresidual capacity and reparability of moderately damaged plastic hinges, with an emphasis on plastic hinges typical of modern moment frame structures. The repair method focussed on is epoxy injection of cracks and patching of spalled concrete. A targeted test program on seventeen nominally identical large-scale ductile reinforced concrete beams, three of which were repaired by epoxy injection following initial damaging loadings, was conducted to support these objectives. Test variables included the loading protocol, the loading rate, and the level of restraint to axial elongation.The information that can be gleaned from post-earthquake damage surveys is investigated. It is shown that residual crack widths are dependent on residual deformations, and are not necessarily indicative of the maximum rotation demands or the plastic hinge residual capacity. The implications of various other types of damage typical of beam and column plastic hinges are also discussed.Experimental data are used to demonstrate that the strength and deformation capacity of plastic hinges with modern seismic detailing are often unreduced as a result of moderate earthquake induced damage, albeit with certain exceptions. Special attention is given to the effects of prior yielding of the longitudinal reinforcement, accounting for the low-cycle fatigue and strain ageing phenomena. A material-level testing program on the low-cycle fatigue behaviour of grade 300E reinforcing steel was conducted to supplement the data available in the literature.A reduction in stiffness, relative to the initial secant stiffness to yield, occurs due to moderate plastic hinging damage. This reduction in stiffness is shown to be correlated with the ductility demand,and a proposed model gives a conservative lower-bound estimate of the residual stiffness following an arbitrary earthquake-type loading. Repair by epoxy injection is shown to be effective in restoring the majority of stiffness to plastic hinges in beams. Epoxy injection is also shown to have implications for the residual strength and elongation characteristics of repaired plastic hinges.

Damage to Wave House on Gloucester Street (Winnie Bagoes Pizza Bar). The roof and left side of the building have collapsed and crumbled into the street, crushing several cars. Emergency personnel have spray painted two of the cars with the word "Clear" to indicate they have been checked for trapped or injured people. The scene has been cordoned off by New Zealand Fire Service tape.

A photograph of the earthquake damage to the Cycle Trading store on Manchester Street. The gable of the store has collapsed, and bricks and other rubble have fallen onto the footpath in front. A car parked on the street has been crushed by the fallen rubble. The word "Clear" has been spray-painted on the front of the car. Wire fencing has been placed around the building as a cordon.

A photograph of the earthquake damage to the Iconic Bar and the former Christchurch City Council offices on Manchester Street. The outer walls of the Council offices and the top storey of Iconic have collapsed, exposing the insides of the buildings. The bricks and other rubble have been cleared from the footpath in front. USAR codes have been spray-painted next to the entrance of Iconic.

Damaged workshops in the Red Bus depot on Fitzgerald Avenue. The brick walls have partially crumbled. In the background is the Cathedral of the Blessed Sacrament, with its dome partly deconstructed. The photographer comments, "This photo was taken recently on Fitzgerald Avenue. Again, it's amazing how close you can get to buildings that look like they are about to collapse. In the background, you can see that work has begun to remove the dome on top of the damaged Cathedral of he Blessed Sacrament".

Shoppers and tourists outside the Simply New Zealand shop in the Re:Start mall. The photographer comments, "The new temporary city mall has been open in Christchurch now for a week. Buildings damaged in the earthquake have been demolished and replaced with cargo containers to create a new, temporary, Cashel Mall. I visited the mall yesterday and was quite impressed with what they have done. The cargo containers have been nicely converted, brightly painted and smartly branded to create some good looking stores".

A photograph of the earthquake damage to the Iconic bar on the corner of Manchester and Gloucester Streets. Large sections of the outer walls have collapsed, the bricks and masonry spilling onto the footpath below, crushing several cars. USAR codes have been spray-painted near the door and a red sticker has been taped above. The red sticker indicates that the building is unsafe to enter.

A photograph submitted by Gaynor James to the QuakeStories website. The description reads, "DTZ building going, 20 July 2011. A small crowd watches the demolition …There is an eerie silence- no excited buzz – people watching yet another part of their history turning into rubble. The wrecking ball, delicately positioned, drops and is followed by the cracking and rending of floor after floor and the debris tumbles down … It starts to clear and an extraordinary sight greets us. Hundreds and hundreds of sheets of paper drift down like giant confetti.".
