Earthquake damaged building on a Walk around the city, May 1, 2014 Christchurch New Zealand. Demolition work on Christchurch's "distinctive" former civic building is under way. The category-2 heritage building was designed by G A J Hart and opened in 1939 as the Miller's department store. It featured the South Island's first escalator, which...

For the first time in November 2011, Christchurch residents finally had the opportunity to see the earthquake-damaged city centre on the Red Zone bus tours organised by CERA. Damage to the Odeon Theatre can be seen out the window.

A view down Cashel Street from the Bridge of Remembrance, showing earthquake damage to several buildings along Cashel Mall. In the background the Hotel Grand Chancellor can be seen, a Christchurch hotel that was badly damaged in the February 2011 earthquake. The collapse of a key supporting shear wall caused the building to visibly lean to one side.

The 2010-2011 Christchurch earthquakes generated damage in several Reinforced Concrete (RC) buildings, which had RC walls as the principal resistant element against earthquake demand. Despite the agreement between structural engineers and researchers in an overall successfully performance there was a lack of knowledge about the behaviour of the damaged structures, and even deeper about a repaired structure, which triggers arguments between different parties that remains up to these days. Then, it is necessary to understand the capacity of the buildings after the earthquake and see how simple repairs techniques improve the building performance. This study will assess the residual capacity of ductile slender RC walls according to current standards in New Zealand, NZS 3101.1 2006 A3. First, a Repaired RC walls Database is created trying to gather previous studies and to evaluate them with existing international guidelines. Then, an archetype building is designed, and the wall is extracted and scaled. Four half-scale walls were designed and will be constructed and tested at the Structures Testing Laboratory at The University of Auckland. The overall dimensions are 3 [m] height, 2 [m] length and 0.175 [m] thick. All four walls will be identical, with differences in the loading protocol and the presence or absence of a repair technique. Results are going to be useful to assess the residual capacity of a damaged wall compare to the original behaviour and also the repaired capacity of walls with simpler repair techniques. The expected behaviour is focussed on big changes in stiffness, more evident than in previously tested RC beams found in the literature.
