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.

Pomeroy's Brewery Inn on Kilmore Street viewed across the Avon River. The bar is green stickered meaning it safe to enter. As a brick building in this condition is fairly rare.

A gap in the wall of an old building on Ferry Road in Woolston. Bricks have collapsed from the side of the building.
A photograph of the earthquake damage to a house on Bealey Avenue near Springfield Road. The walls have crumbled, the bricks spilling onto the footpath in front. the ceiling of the building has been braced with scaffolding. Wire fencing and police tape has been placed around the building as a cordon.
A photograph of the earthquake damage to the former Canterbury Public Library on the corner of Hereford Street and Cambridge Terrace. The bricks in the corner of the building have crumbled and masonry can be seen on the footpath below. Wire fences have been placed around the building as a cordon.
A photograph of the earthquake damage to Charlie B's Backpackers on Madras Street. The front of the building has collapsed, the bricks and other rubble spilling onto the road and footpath in front. Many of the walls inside the top storey of the building are now hanging loose from the ceiling.

A photograph of the earthquake damage to Café Valentino on Colombo Street. The façade of the closest section of the building has collapsed and the bricks have spilled onto the awning below. The same section of the awning has broken under the weight of the bricks and is resting against the ground. Bricks and other rubble cover the other sections of the awning and have spilled onto the footpath and street in the distance.
