[摘要]  凯纳商务广场主楼54层，高184m，采用全部落地剪力墙结构体系，超过B级最大适用高度22.7%。剪力墙结构体系自重大，抗侧刚度大，导致地震作用较大。为保证结构的延性，工程采用基于性能的抗震设计方法，针对超限情况和结构体系，提出性能设计目标，并采用不同的计算软件进行结构分析，以提高设计的可靠性，避免抗震安全隐患。结果表明，工程抗震性能较好，结构体系安全可行。

Abstract:  Kaina Business Plaza with 54 stories is a super high structure,and the roof height is 184m.  It applies the shear wall structure system witbout tranter remembers,which exceeds the B-level height 22.7%. The self weight and lateral stiffness of the shear wall structure system is so large that the seismic influence is notable. Aimed at the height beyond the code-specification and the structure system of the project, the performancr based design method is adopted, in order to guarantee the reliability of the seismic design and ensure the earthquake safety. The performance objectives are recommendations,and the structure is analyzed with some different calculating pmgrams. Based on the analysis,the seismic performance of the structure system is good,and the structure is safe and reliable.
