[摘要] 上海天山路项目采用框架剪力墙结构，其底部带有一个大裙房和一个长悬臂，给结构带来较多超限项，结构属于超限结构，按规范进行性能设计时，大震不屈服状态下，剪力墙出现较大拉力，结构可能有较大损伤，基于此，本文对结构采用Perform-3D进行动力弹塑性分析，采用基于美国ASCE-06可接受的塑性变形准则，定义了梁、柱剪力墙的IO、LS和CP性能目标，同时提出对剪力墙和柱基于抗剪弹性的时程设计方法，找出结构的薄弱部位，从而有针对性地采取加强措施。计算结果表明，结构的各项性能指标未超过预定的性能指标，结构没有出现较大损伤，能满足性能设计的要求，同时满足规范大震不倒的性能目标。

Abstract: Frame-shear wall structure is used in the project of Tianshan Road in Shanghai with a large podium and a long cantilever. It beyonds many code limits. A large tensile-force will appear in the shear-wall according to performance design under elastic rare earthquake, and the serious damage may occur. To find the weak parts and the corresponding reinforcement measures to be adopted, dynamic elastic-plastic analysis using Perform-3D was carried out in this structure. The detail parameters of lugh-rise building was calculated based on the standard of American ASCE-06, and the performance goal such as IO, LS and CP was assigned to the beam, column and shear-wall.  The method of time-lustory design was applied to column and shear-wall based on the elastic shear capacity. The results show that the performance goal defined in advance is achieved and meet the code requirements.
