摘要
利用空间弹塑性时程分析软件EPDA,采用Taft波,EL centrol波,兰州人工波分别沿x方向、y方向、45°方向分别输入地震波,对高烈度区某空间框架结构进行了弹塑性时程分析,找出其薄弱层的位置,给出了塑性铰出现的位置及规律,通过对计算结果的分析,给出了一些有益的结论,供设计人员参考.
Based on the analysis of a space elasticplastic timehistory procedure EPDA,the aseismatic behavior of a space frame structure in high earthquake intensity zone under seldom occurred earthquake is studied with timehistory analysis method.And in this analysis,several acceleration records of Taft earthquake wave,Lanzhou artificial earthquake wave and Elcentrol earthquake wave are applied as the input wave in the direction of x,y and 45 degree.The location law of weak stories and the distribution rule of the plastic hinge are analysed in different stages.After analysing the results of the calculation,some valuable suggestions are concluded and can be used for reference to designer.
