［摘要］三金潭车辆段综合开发项目地处抗震不利地段，A地块有11栋塔楼和裙房（含商业、社区服务中心及幼儿园），11栋塔楼均采用钢筋混凝土剪力墙结构体系，且有9栋塔楼为B级高度，存在高度超限和扭转不规则、凹凸不规则两项平面不规则情况。综合考虑场地特点、超限程度及分析结果，设定住宅塔楼的抗震性能目标为D级。采用YJK，ETABS和PERFORM-3D等软件对超高层住宅群进行了小震、中震和大震作用下的计算分析。结果表明，塔楼结构布置合理，地基处理及加强措施安全可靠，结构整体能满足设定的抗震性能目标。

Abstract:The comprehensive development project of SanjinTan depot is located in the section with unfavorable seismic resistance conditions. There are 11 towers and podiums (including commercial, community service center and kindergarten) in plot A. All the 11 towers adopt reinforced concrete shear wall structural system, and 9 towers are  grade B height. There is the out-of-code condition of height and there are two kinds of plane irregularities such as torsion irregularity and concave convex irregularity. Considering the site characteristics, out-of-code degree and analysis results, the seismic performance objective of residential tower was set as grade D. By using YJK, ETABS and PERFORM-3D softwares, the calculation and analysis were conducted on the super high-rise residential complex under the action of frequent earthquake, fortification earthquake and rare earthquake. The results show that the layout of the tower structure is reasonable, the foundation treatment and strengthening measures are safe and reliable, and the overall structure can meet the set seismic performance objectives.

Keywords:out-of-code high-rise building; foundation treatment; performance-based design; dynamic elastic-plastic time-history analysis
