As part of a seismic retrofit scheme, surface bonded glass fiber-reinforced polymer (GFRP) fabric was applied to two unreinforced masonry (URM) buildings located in Christchurch, New Zealand. The unreinforced stone masonry of Christchurch Girls’ High School (GHS) and the unreinforced clay brick masonry Shirley Community Centre were retrofitted using surface bonded GFRP in 2007 and 2009, respectively. Much of the knowledge on the seismic performance of GFRP retrofitted URM was previously assimilated from laboratory-based experimental studies with controlled environments and loading schemes. The 2010/2011 Canterbury earthquake sequence provided a rare opportunity to evaluate the GFRP retrofit applied to two vintage URM buildings and to document its performance when subjected to actual design-level earthquake-induced shaking. Both GFRP retrofits were found to be successful in preserving architectural features within the buildings as well as maintaining the structural integrity of the URM walls. Successful seismic performance was based on comparisons made between the GFRP retrofitted GHS building and the adjacent nonretrofitted Boys’ High School building, as well as on a comparison between the GFRP retrofitted and nonretrofitted walls of the Shirley Community Centre building. Based on detailed postearthquake observations and investigations, the GFRP retrofitted URM walls in the subject buildings exhibited negligible to minor levels of damage without delamination, whereas significant damage was observed in comparable nonretrofitted URM walls.

About two hundred of those who lost loved ones in collapsed buildings in Christchurch's 2011 earthquake, heard an apology from the city's mayor, Lianne Dalziel yesterday. A royal commission in to faulty buildings found serious errors by engineers and the Christchurch City Council 185 people died during the earthquake on the 22nd of February, 2011. David Selway who lost his sister Susan Selway in the CTV Building, said it was good to hear a heartfelt apology from the mayor for the role her council played in signing off the building as safe.

A video of Press journalist Martin Van Beynen talking about the Canterbury Television Building which collapsed during the 22 February 2011 earthquake. Beynen investigates the construction manager of the building, Gerald Shirtcliff, who allegedly faked an engineering degree and stole the identity of an engineer he knew in South Africa. The video also includes footage of Shirtcliff giving evidence about the CTV Building at the Canterbury Earthquake Royal Commission.
