摘　　要：天朗海峰国际中心塔楼采用现浇钢筋混凝土部分框支剪力墙结构。采用基于性能的抗震设计方法,利用承载力与变形验证不同水准下结构与构件的抗震性能,包括小震弹性计算,中震弹性及中震不屈服构件验算,以及罕遇地震下的弹塑性分析。提出了相应的超限设计措施,使结构能够实现预定的性能目标。同时根据工程的风洞试验结果进行风振时程分析,并将分析结果与规范风静力荷载计算得出的结果比较,取较不利者进行抗风设计。Partial frame-supported shear wall structure is adopted for the Synonym Haifeng.Performance based seismic design was proposed.Structure and component performance were verified based on bearing capacity and deformation under different levels,including elastic analysis under frequent earthquake,un-yielding and elastic check of structure components under medium earthquake,static and dynamic inelastic analysis under rare earthquake.Series of relevant were suggested to make sure the performance object can be well realized.Besides,wind induced vibration time history analysis was carried out and the analysis results were compared with the results calculated according to the codes,and the unfavorable condition was taken considered in the wind-resistant design.
