摘　　要：贵阳世界贸易中心塔楼结构高度196.30 m,采用框架-核心筒结构体系,属于B级高度超高层建筑,同时在37层及以上存在体型收进、24夹层存在局部穿层柱等不规则项。采用基于性能的抗震设计方法,设定结构抗震性能目标要求为C级,进行整体结构弹性计算、弹性时程分析、抗震性能验算以及罕遇地震作用下的动力弹塑性分析,结合计算分析结果,在采取有针对性的抗震加强措施下确保结构安全可行。Guiyang World Trade Center,with a height of 196.30 meters and a frame-core wall structure,is classified as a super high-rise building of Grade B height. It has setbacks starting at the 37 th floor as well as columns across the 24 th interlayer and other irregularities. A performance-based seismic design method is adopted,with the seismic performance target set at Grade C. Through the elasticity calculations of the overall structure,elastic time history analysis,seismic performance checking,and dynamic elastic-plastic analysis under rare earthquake conditions,targeted anti-seismic strengthening measures are taken to ensure the safety and feasibility of the structure.
