Damage to Lyttelton following the 22 February 2011 earthquake. The fish and chip shop on London Street (centre) has a collapsed gable and awning. Bricks, plaster and wood are lying where they fell on the footpath, as well as the broken sign. To the left is the Lava Bar which suffered severe structural damage after the earthquake. To the right, the Coastal Living store can be seen which was open after the September earthquake but pulled down after February.

A video of an interview with Zak and Alasdair Cassels about the development of the historic tannery site in Woolston. The Cassels are developing the site into a Victorian-style arcade which will house up to 70 tenants, including bars, restaurants, a music venue, gift shops, fashion stores, a hair salon, a Pilates studio, a tattoo parlour, and an art gallery. The video also includes an interview with Sarah Odering, the manger of Dead Set.

A major lesson from the 2011 Christchurch earthquake was the apparent lack of ductility of some lightly reinforced concrete (RC) wall structures. In particular, the structural behaviour of the critical wall in the Gallery Apartments building demonstrated that the inelastic deformation capacity of a structure, as well as potentially brittle failure of the reinforcement, is dependent on the level of bond deterioration between reinforcement and surrounding concrete that occurs under seismic loading. This paper presents the findings of an experimental study on bond behaviour between deformed reinforcing bars and the surrounding concrete. Bond strength and relative bond slip was evaluated using 75 pull-out tests under monotonic and cyclic loading. Variations of the experiments include the loading rate, loading history, concrete strength (25 to 70 MPa), concrete age, cover thickness, bar diameter (16 and 20 mm), embedded length, and the position of the embedded bond region within the specimen (deep within or close to free surface). Select test results are presented with inferred implications for RC structures.
