某超高层框筒结构的抗震性能分析

本文以某超限框架-核心筒结构为例,通过对该结构在多遇地震下的弹性分析、设防烈度下的等效弹性计算以及罕遇地震下等效弹性分析和弹塑性分析,并对开洞楼层的楼板应力分析,检验其抗震性能。分析结果表明,通过加强措施后,能达到期望的性能目标,可供同类工程参考。

Seismic Performance Analysis of a Super High-rise Frame-tube Structure

Taking a frame-tube structure as an example, this study carries out the elastic analysis under the frequent earthquake, equivalent elastic calculation under fortiifcation intensity earthquake, equivalent elastic and elastic-plastic analysis under the rare earthquake and stress analysis of openings layer’s lfoor, to test its seismic performance. Analysis results indicate that it can reach the expected performance objectives after reinforce measures were performed, and it also provides reference to similar projects.
