Numerical Investigation on the Collapse of the Ctv Building Caused By the 2011 New Zealand Earthquake

Abstract eng:
A six-story high, reinforced concrete (RC) framed structure called the Canterbury Television (CTV) building collapsed totally with only the north-core wall remained standing (Fig.1), due to the earthquake of magnitude 6.3 which occurred in New Zealand on 22nd of February, 2011. Many overseas students including Japanese students died in the event. Hyland and Smith [1] investigated on the possible cause of the collapse. They concluded that the building swayed and twisted violently. Once the column on the mid to upper levels on the east face failed, other columns rapidly became overloaded and failed. Then the beams and floor slabs fell down and broke away from the north-core.
