A photograph of the earthquake damage to a building on Lichfield Street. Masonry from the top section of the building has broken away and spilled onto the footpath below. A red sticker has been placed on the door, indicating that the building is unsafe to enter. USAR codes have been spray-painted on the column and window to the right.

A photograph of the earthquake damage to the Piko Wholefoods Building on the corner of Kilmore and Barbadoes Street. Sections of the top storey of the building have collapsed and the bricks and other rubble have spilled onto the footpath below. Steel fences have been placed around the building as a cordon.

A photograph of an earthquake-damaged building on Acton Street. The closest section of the outer wall has collapsed, the bricks and other rubble spilling onto the pavement in front. A boat which was being stored inside has toppled over and is now sticking out of the building. Several cars, also stored inside the building, are visible.

A photograph of the earthquake damage to a building on Hereford Street. A column on the right side of the building has snapped and the side wall has pulled away from the building. USAR codes have been spray-painted on one of the windows on the bottom storey. In the foreground there is a police car.

A photograph of the earthquake damage to the Asko Design building on Victoria Street. The top of the facade has crumbled and fallen into the street, taking the awning with it. The side wall has also collapsed, exposing the inside of the building. Wire fencing and tape have been used to cordon the buildings off.

A photograph of earthquake damage to the Kenton Chambers Building on Hereford Street. Cracks have formed between the windows of the building. A section of the bottom storey has collapsed, the bricks spilling onto the footpath. Steel fencing and road cones have been placed on the street in front of the building as a cordon.

This poster presents preliminary results of ongoing experimental campaigns at the Universities of Auckland and Canterbury, aiming at investigating the seismic residual capacity of damaged reinforced concrete plastic hinges, as well as the effectiveness of epoxy injection techniques for restoring their stiffness, energy dissipation, and deformation capacity characteristics. This work is part of wider research project which started in 2012 at the University of Canterbury entitled “Residual Capacity and Repairing Options for Reinforced Concrete Buildings”, funded by the Natural Hazards Research Platform (NHRP). This research project aims at gaining a better understanding and providing the main end-users and stakeholders (practitioner engineers, owners, local and government authorities, insurers, and regulatory agencies) with comprehensive evidence-based information and practical guidelines to assess the residual capacity of damaged reinforced concrete buildings, as well as to evaluate the feasibility of repairing and thus support their delicate decision-making process of repair vs. demolition or replacement.

The sequence of earthquakes that has affected Christchurch and Canterbury since September 2010 has caused damage to a great number of buildings of all construction types. Following post-event damage surveys performed between April 2011 and June 2011, the damage suffered by unreinforced stone masonry buildings is reported and different types of observed failures are described. A detailed technical description of the most prevalently observed failure mechanisms is provided, with reference to recognised failure modes for unreinforced masonry structures. The observed performance of existing seismic retrofit interventions is also provided, as an understanding of the seismic response of these interventions is of fundamental importance for assessing the vulnerability of similar strengthening techniques when applied to unreinforced stone masonry structures.
