This paper presents preliminary results of an experimental campaign on three beam-column joint subassemblies extracted from a 22-storey reinforced concrete frame building constructed in late 1980s at the Christchurch’s Central Business District (CBD) area, damaged and demolished after the 2010-2011 Canterbury earthquakes sequence (CES). The building was designed following capacity design principles. Column sway (i.e., soft storey) mechanisms were avoided, and the beams were provided with plastic hinge relocation details at both beam-ends, aiming at developing plastic hinges away from the column faces. The specimens were tested under quasi-static cyclic displacement controlled lateral loading. One of the specimens, showing no visible residual cracks was cyclically tested in its as-is condition. The other two specimens which showed residual cracks varying between hairline and 1.0mm in width, were subjected to cyclic loading to simulate cracking patterns consistent with what can be considered moderate damage. The cracked specimens were then repaired with an epoxy injection technique and subsequently retested until reaching failure. The epoxy injection techniques demonstrated to be quite efficient in partly, although not fully, restoring the energy dissipation capacities of the damaged specimens at all beam rotation levels. The stiffness was partly restored within the elastic range and almost fully restored after the onset of nonlinear behaviour.

A scheme called Crack'd for Christchurch wants to make a beautiful memorial out of the fine china broken in the earthquake. Jenny Cooper is one of a group of people who plan to create an inner-city mosaic that is an art work in its own right, but also acts as a memorial to old Christchurch.

A photograph of the earthquake damage to the Loyal Benevolent Lodge on Canon Street. Bricks at the top of the façade have crumbled and fallen to the ground, bringing the awning with them. Large cracks can be seen in the remaining brick wall.

A house on Avonside Drive showing damage from the 4 September 2010 earthquake. Numerous cracks in the masonry can be seen, and several sections of brick have fallen off the walls. The building's porch has also collapsed. A pile of dried liquefaction is visible in the driveway.

A house on Acland Avenue in Avonside that has been abandoned due to damage from the 4 September 2010 earthquake. The house's front garden has become overgrown and weeds have grown up through the cracks in its driveway. Its chimneys have collapsed and have been weather proofed with tarpaulins.
