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.

A video about businesses in the Christchurch central city Red Zone. The Red Zone has now been renamed the Rebuild Zone. The video shows businesses which have remained untouched since the 22 February 2011 earthquake, including the Camelot Hotel and the i-SITE visitor centre in Cathedral Square, Subway on High Street, Jeans West on High Street, Time Zone on Colombo Street, Comics Compulsion on Manchester Street, Mortgage Solutions mortgage brokers on the corner of Hereford and Manchester Streets, Pocha Bar and Restaurant off Lichfield Street, and a fabric store on Lichfield Street.
