Patchwork quilts wrapped around the concrete slabs used to stabilise a broken wall on Winchester Street. They make it look snug despite the snow. Many projects like this have cropped up around Canterbury in an effort to brighten the earthquake environment.

This is how the building looked when it was built - fine indeed! democam.iopen.co.nz/ An engineer who owns a similar building in Dunedin, and is willing to put money into this building's restoration, is sure it could be stabilised, just like the Railway Clock Tower. And the t...

A photograph of the earthquake-damaged Oxford Terrace Baptist Church. Steels bracing has been used to stabilise the front of the building. Crumbled masonry and other rubble is still lying in front. Wire fences have been placed around the building site as a cordon.

A photograph captioned by BeckerFraserPhotos, "The failed column near the south-east corner of the ground floor of the Hotel Grand Chancellor. This corner of the building slumped 700mm when this column and a nearby sheer wall failed. Scaffolding was erected all around it and then sprayed with concrete to stabilise the building".

The Catholic Cathedral of the Blessed Sacrament is a category 1 listed heritage building constructed largely of unreinforced stone masonry, and was significantly damaged in the recent Canterbury earthquakes. The building experienced ground shaking in excess of its capacity leading to block failures and partial collapse of parts of the building, which left the building standing but still posing a significant hazard. In this paper we discuss the approach to securing the building, and the interaction of the structural, heritage and safety demands involved in a dynamic seismic risk environment. We briefly cover the types of failures observed and the behaviour of the structure, and investigate the performance of both strengthened and un-strengthened parts of the building. Seismic strengthening options are investigated at a conceptual level. We draw conclusions as to how the building performed in the earthquakes, comment on the effectiveness of the strengthening and securing work and discuss the potential seismic strengthening methods.
