A view looking south down Durham Street during the aftermath of the 22 February 2011 earthquake. On the left are the ruins of the historic stone Provincial Council Legislative Chamber. The building's roof and walls have already collapsed, as has the scaffolding which was erected to repair it after the 4 September 2010 earthquake. An aftershock has caused masonry to dislodge from the building, sending dust into the air.

Case study unreinforced masonry (URM) buildings that were seismically retrofitted prior to the 2010/11 Canterbury earthquake sequence and exhibited successful performance during these earthquakes are presented herein. Selected buildings were divided into the following categories based on size and complexity: (1) simple, single storey box type buildings (i.e. electrical substations), (2) common and simple commercial buildings, and (3) large and complex clay brick and stone URM buildings. The retrofitted case study URM buildings were evaluated based on overall structural seismic performance as well as the categories of initial seismic design, heritage preservation, architectural appeal, and cost. Detailed observations of 4 representative case study buildings and a summary of findings are reported herein. http://db.nzsee.org.nz/2017/Orals.htm

A crane dismantles the top storey of Fuze Restaurant and Cafe, which was formerly the Harbour Board Offices building. It was constructed in 1880 from brick and Quail Island stone. It stands on the corner of Oxford Street and Norwich Quay in Lyttelton.

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.

An aerial photograph looking west over the Arts Centre and Christ's College towards Hagley Park. The photograph has been captioned by BeckerFraserPhotos, "At the centre of this photo is a group of heritage stone buildings. Canterbury Museum and Christ's College were extensively earthquake strengthened prior to the EQs and re-opened to the public relatively quickly. The Arts Centre is undergoing extensive renovations. Hagley Park and the Botanic Gardens provide a richly colourful surrounding to these historic buildings".

A photograph captioned by BeckerFraserPhotos, "The Octagon Live Restaurant, formerly Trinity Congregational Church, on the corner of Manchester and Worcester Street. This was further damaged in the 23 December 2011 earthquake when a big piece of the rose window fell out".
