Damage to buildings along Norwich Quay in Lyttelton. To the left is the Lyttelton Hotel with a crumbled top. Bricks have fallen on the awning and all along the footpath. To the right is a cafe that was damaged severely in the earthquake. The front wall of the top storey has crumbled onto the street, crushing a car. Wire fencing and road cones have been used to create a cordon around the buildings.

A photograph of the earthquake damage to R&R Sport on the corner of Colombo and Tuam Streets. Most of the side wall has crumbled, the bricks spilling onto the footpath below. Plywood and plastic sheeting has been used to weather proof the building. Wire fencing and road cones have been placed around the building as a cordon. A cherry picker is parked on the footpath in between the building and the fence.

A photograph of a Wellington Emergency Management Office Emergency Response Team member talking to a member of the Professional Building Services on Gloucester Street. In the background is the Press House building with many cracks in the façade. Bits of bricks and other debris are scattered across the footpath. Some of the windows above the facade have broken. USAR codes have been spray-painted on one of the bottom-storey windows.

A photograph of the earthquake damage to the Country Theme store on the corner of Manchester and St Asaph Streets. Sections of the second storey walls have crumbled, and the bricks have fallen onto the footpath below. Wire fences have been placed around the building as a cordon. Red stickers on the front door and the wire fence indicate that the building is not safe to enter.

A photograph of members of the Wellington Emergency Management Office Emergency Response Team examining an earthquake-damaged building on Acton Street. The closest section of the outer wall has collapsed, and the bricks and other rubble have fallen 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-damaged buildings and rubble on Colombo Street near the intersection of St Asaph Street. The walls of the top storey of the buildings to the left have crumbled, and bricks and other rubble have fallen onto the footpath and road below. Wire fencing and police tape have been placed across the street as a cordon. An excavator from Daniel Smith Industries Ltd is parked in front of the fence.

This thesis describes the strategies for earthquake strengthening vintage clay bricks unreinforced masonry (URM) buildings. URM buildings are well known to be vulnerable to damage from earthquake-induced lateral forces that may result in partial or full building collapse. The 2010/2011 Canterbury earthquakes are the most recent destructive natural disaster that resulted in the deaths of 185 people. The earthquake events had drawn people’s attention when URM failure and collapse caused about 39 of the fatality. Despite the poor performance of URM buildings during the 2010/2011 Canterbury earthquakes, a number of successful case study buildings were identified and their details research in-depth. In order to discover the successful seismic retrofitting techniques, two case studies of retrofitted historical buildings located in Christchurch, New Zealand i.e. Orion’s URM substations and an iconic Heritage Hotel (aka Old Government Building) was conducted by investigating and evaluating the earthquake performance of the seismic retrofitting technique applied on the buildings prior to the 2010/2011 Canterbury earthquakes and their performance after the earthquakes sequence. The second part of the research reported in this thesis was directed with the primary aim of developing a cost-effective seismic retrofitting technique with minimal interference to the vintage clay-bricks URM buildings. Two retrofitting techniques, (i) near-surface mounted steel wire rope (NSM-SWR) with further investigation on URM wallettes to get deeper understanding the URM in-plane behaviour, and (ii) FRP anchor are reported in this research thesis.
