摘要:瑞虹新城9号地块的T11-12号楼为部分框支剪力墙结构，通过性能化设计，结构实现了良好的承载力和延性。对在静力弹塑性分析中发现的问题，采取了加强转换层上部墙肢延性的设计手段作为解决措施；同时也给工程师带来启示：构件设计必须服从于整体结构的屈服机制和性能目标，在承载力和延性上做出合理的平衡。

Abstract: The structural system of T11-12 building in Rainbow Lot 9 is frame-supported shearwall. With Performance-based design method, it can be proved that the strength and ductility of structure were favorable. According to the result of Pushover analysis, the ductility design was adopted for the shearwall above transfer story. By the above work, it is showed that seismic performance objectives and yield mechanism should be considered correctly, and the structure should be balanced between strength and ductility.
