L型平面不规则结构的地震反应分析和评估

摘要

The modal analysis of an L-type structure of planar irregularity is made with SAP2000 to obtain the dy⁃namic characteristics of the structure. Besides, using both seismic response spectrum analysis and time procedure analysis, the result of structure response is numerically simulated so that the anti-seismic property is definite to provide reference for the design.%通过sap2000有限元软件，对建立的L型平面不规则结构进行了模态分析，得到了结构自身的动力特性。在此基础上，利用反应谱分析和时程分析对结构响应的结果进行数值模拟，得到了结构的抗震性能，为设计工作提供了一定参考。
