Aiming at the most structurally-concerned aspects in this building, numerous plans were compared, an in-depth analysis was performed and detailed calculations were carried out, including nonlinear analysis, joint analysis, elasto-plastic analysis under rare earthquake, wind vibration analysis and construction simulation, in order to achieve the safety and reliability of the structure. The project has passed the expert panel review for seismic and is now in the construction phase.Keywords: total design; diagrid; post-buckling strength; overall stability; vertical discontinuous; steel brace core作者簡介：雷強，碩士，一級注冊結構工程師，Email: qiang.lei@arup.com。參考文獻［1］GB 50011—2010 建筑抗震設計規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2010.［2］佛山公共文化綜合體坊塔結構抗震專項審查報告［R］. 深圳：奧雅納工程顧問（上海）公司深圳分公司，2011.［3］GB 50017—2003 鋼結構設計規(guī)范［S］. 北京：中國計劃出版社，2003.［4］陳紹蕃.鋼結構穩(wěn)定設計的新進展［J］. 建筑鋼結構進展，2004，6(2)：1-13.［5］FEMA356 Prestandard and commentary for the seismic rehabilitation of buildings［S］.
