In this study, we investigated the behaviors of the Canterbury Television (CTV) building which totally collapsed, with only the north-core wall remained standing, during the New Zealand earthquake that occurred on February 22, 2011. A seismic collapse analysis code for RC framed buildings developed using the ASI-Gauss technique [1] is used to simulate the collapse phenomenon. A finite element model of the CTV building is constructed based upon the actual structural drawing of the building. The result of a static pushover analysis showed its unbalanced strengths toward the EW and NS directions due to its biased distribution of anti-seismic walls. Furthermore, the result of a dynamic collapse analysis showed a collapse behavior of the same feature with the investigation report, with a twist motion clearly observed around the elevator shaft connected at the north part of the building.
