The CTV Building was the headquarters of Canterbury Television (locally known as CTV) and other companies. Located in the Christchurch Central City on the corner of Cashel and Madras Streets, it became one of the symbols of the February 2011 Christchurch earthquake. 115 people lost their lives when the CTV Building collapsed during the 2011 earthquake; more than half of the earthquake's total fatalities. ==History== The CTV Building was designed and constructed in about 1986.〔 Christchurch City Council gave building consent in September 1986. Building codes for earthquake design changed frequently in New Zealand following the 1931 Hawke's Bay earthquake (in 1935, 1965, 1976, 1984 and 1992). A significant change in design philosophy was the change from non-ductile design of a reinforced concrete structure to a ductile approach, where it is expected that building joints yield in design earthquake events, which might make a structure uninhabitable but without it collapsing. A new reinforced concrete standard emphasising ductility came into effect in New Zealand in 1982.〔 Stefano Pampanin, an Associate Professor at the University of Canterbury who teaches in structural and seismic design,〔(【引用サイトリンク】url=http://www.civil.canterbury.ac.nz/staff/spampanin.shtml )〕 described the non-ductile philosophy as "an obsolete design based on the levels of knowledge and code provisions that existed before the mid-1980s".〔 The structural design engineer was Alan Reay Consultants (named after the company's owner) and the architect was Alun Wilke Associates Architects, both of which are firms based in Christchurch.〔 In September 2012 it was discovered the man who supervised the building's construction had faked his engineering degree. Gerald Shirtcliff had stolen the identity of a retired engineer based in the UK, William Fisher. The pair had been friends in the 1960s, and Shirtcliff stole Fisher's degree by adopting his name. It was later discovered Shirtcliff's father had done most of the work on his masters in highway engineering. The CTV Building was inspected by engineers after the 4 September 2010 Canterbury earthquake and after the 26 December 2010 4.9 magnitude aftershock. On both occasions, the building was declared safe, having suffered only superficial damage.〔 〕 The building collapsed in the 22 February 2011 earthquake and due to its high death toll of over 100 people has become one of the symbols of the earthquake. The building was owned since 1991〔 by Madras Equities, a company owned by shareholders Russell Warren Ibbotson and Lionel Walter Hunter. Hunter lost a friend in the building and told a reporter if he had known that there was anything wrong with the building, "I would have pushed it over myself."〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「CTV Building」の詳細全文を読む スポンサード リンク
