A video of a protest against the demolition of the Majestic Theatre on Manchester Street. The video includes an interview with Christchurch City Councillor Yani Johanson. Johanson talks about how the lack of heritage recovery programme in Christchurch has meant that many heritage buildings have destroyed, mainly through the fast-tracking of consenting by the government. Johanson asks that the government returns normal democratic decision making over heritage to the Christchurch City Council so that the public can have a say. The video also includes footage of the Wizard and a protester speaking outside the Majestic Theatre.
Topics - scientists are wondering how the light gets out. Maybe there is a cosmic crack in everything, because in the Journal Astrophysical Letters it is noted that there is a huge deficit of light in the universe. Owners of heritage apartments in Auckland face becoming "impoverished" according to a high-profile real estate figure, because of new laws around earthquake strengthening. Martin Dunn of City Sales says the Building Amendment Bill is "overkill". He says those trying to sell heritage apartments are having a difficult time because of the new rules. Jim Anderton, has again raised the issue of whether the Christchurch Cathedral has to come down.
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.
