摘要
应用Matlab软件开发出的计算程序,利用El-Centro波及宁河地震波平动加速度分量获得其地震波扭转分量。通过ANSYS软件建立的异形框架柱结构空间弹塑性分析模型,对结构进行多维(双向水平加扭转方向)地震波加速度分量的弹塑性时程分析。结果表明,扭转地震分量对异形柱结构的影响较大,设计时应充分考虑其对结构效应的增大影响。
Obtained the rotational components from the translational components of El-Centro wave and Ninghe wave using the author＇s procedure of Matlab software,then the specially-shaped column frame＇s space elastoplasticity model was established using the ANSYS software,and the time history analysis was carried on when the rotational component and the translational components were input to the above model.The result indicated that the specially-shaped column structure is very sensitive to the multi-dimensional seismic including rotational seismic component,the enlarged effect should be considered fully when the specially-shaped column structure was designed to improve it＇s seismic safety.
