地震扭转分量对框架影响的数值分析

摘要

采用MATLAB软件开发计算程序,用汶川地震—地震波的平动分量计算得到转动分量.在此基础上,采用ABAQUS有限元分析软件,通过对一对称框架结构进行数值计算,研究结果表明:地震波的扭转分量对对称框架结构的位移影响较大,在抗震设计中不可忽视.%This paper gets the torsional component of Wenchuan wave through the Matlab calculationsoftware. On this basis, using ABAQUS FEA software, through the numerical calculation of a symmetricalframe, we can draw a conclusion that the seismic tomional components have significant impact on displace-ment of symmetric frame, and it can' t be ignored in seismic design.
