［摘要］昆明江东和谐广场B，D栋建筑总高度249.85m，下部为框架-核心筒结构，上部为钢结构，属超限高层建筑。针对结构高度超限，采用基于性能的抗震设计，并对结构进行弹塑性分析，在宏观上把握结构薄弱部位，有针对性地采取加强措施。计算结果表明，结构的工作状态和性能均能达到设计的预期性能目标和规范要求。

Abstract:Two super high-rise buildings(B&D) of Jiangdong Hexie Square are 249.85 meters height and  beyond the code limits. The frame-core wall system is used in the lower part, and steel structure is used in the upper part. Dynamic elastic-plastic analysis was carried on by performance-based seismic design. The weak members could be distinguished on the whole and the strengthening measures were adopted. The results show that the structure can meet the design goals of seismic performance and code requirement.
Keywords:super high-rise building; frame-core wall structure; beyond code limits; performancebased seismic design; dynamic elastic-plastic analysis; Perform-3D
