［摘要］对新天地国际大厦塔A高层框架-剪力墙结构进行了静力弹塑性分析。计算结果表明，结构在罕遇地震作用下，部分构件屈服。最大层间位移角为1/193，满足规范规定的变形要求，并对结构性能进行评估。利用小震作用下振型分解反应谱法的计算结果，提出能力谱小震性能点的周期修正法。

Abstract:The static nonlinear analysis was conducted on tower A of New World International Building, which is a complex frame-shear wall structure. The results show that parts of structural members are yielding under rare earthquake. The biggest story drift is 1/193 which can satisfy deformation demands of design code, and  the  structure capability is assessed. According to the results of mode-superposition response spectrum method under small earthquake, advance modified period method of performance point on capacity spectrum curve was put forward.

Keywords:static nonlinear analysis; target displacement; capacity spectrum curve; performance point
