［摘要］苏州龙湖某综合体建筑总高度218-5m，结构高度198-5m，采用钢筋混凝土（RC）框架-核心筒结构体系，是具有扭转不规则、偏心布置、楼板局部不连续、竖向刚度突变等不规则项的超B级高度高层建筑。采用抗震性能化设计方法，根据设定的抗震性能目标，对主体结构进行了小震、中震和大震性能计算。同时针对项目的特点，进行了大震静力和动力弹塑性分析、大开洞楼板专项分析等。计算结果表明，结构体系合理、安全、可靠，能够满足预定的性能目标，大开洞楼板可实现中震不屈服。

Abstract:The total height of a Longhu complex building in Suzhou  is 218-5m and the structural height is 198-5m. Structural system of RC frame-corewall is adopted. It is an out-of-code high-rise building exceeding B-level height requirement and it has irregular items including irregular torsion, eccentric arrangement, local floor discontinuity and vertical stiffness mutation. Performance-based seismic design method was adopted and calculations under the frequent earthquake, fortification earthquake and rare earthquake were conducted on the main structure according to predetermined seismic performance objectives. At the same time, according to the characteristics of the project, static and dynamic elastic-plastic analysis under rare earthquake and specific analysis of the floor with large openings were carried out. The calculation results show that the structural system is reasonable, safe and reliable, and can meet the predetermined performance objectives. The floor with large openings can achieve the non-yielding objective under fortification earthquake.

Keywords:super high-rise structure; performance-based seismic design; static elastic-plastic time-history analysis; dynamic elastic-plastic time-history analysis; slab with large openings  specific mechanical behavior analysis
