In 1861, the city of Christchurch would have been virtually unrecognisable to a 21st century resident. Buildings were scattered sparsely throughout what is now the central business district and dirt roads and low fences traversed a landscape that was more grassland … Continue reading →

Residents of some Christchurch suburbs could be in for bigger than expected rates rises after the first QV valuations since the earthquakes. The average Christchurch home now has a rating value of 455 thousand dollars, which translates into an annual rates bill of just over two thousand dollars.

The Catholic Cathedral is classified as a category 1 listed heritage building constructed largely of unreinforced stone masonry, and was significantly damaged in the recent Canterbury earthquakes of 2010 and 2011. In the 2010 event the building presented slight to moderta damage, meanwhile in the 2011 one 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 develop the earthquake analysis of the building by 3D numerical simulations, and the results are compared/calibrated with the observed damage of the 2010 earthquake. Very accurate records were obtained during both earthquakes due to a record station located least than 80 m of distance from the building and used in the simulations. Moreover it is included in the model the soil structure interaction because it was observed that the ground and foundation played an important role on the seismic behavior of the structure. A very good agreement was found between the real observed damage and the nonlinear dynamic simulations described trough inelastic deformation (cracking) and building´s performance.

A copy of a letter from Empowered Christchurch to Peter Sparrow, Director of Building Control and Rebuild at the Christchurch City Council, sent on 23 October 2014. The letter is a response to another letter sent by Peter Sparrow to Empowered Christchurch regarding existing use rights and exemptions from a building consent. In this letter, Empowered Christchurch requests furthur clarification from the Christchurch Building Consent Authority about these concepts.
