摘要

讨论了获得扭转地震加速度的原理,并通过编制Matlab程序获得了LIMON COSTA RICA地震波的绕z轴扭转加速度分量。对一个12层基础隔震结构进行ANSYS软件时程分析,对结构模型输入LI-MON COSTA RICA地震波扭转加速度分量以及平动加速度分量,进行时程分析,研究结果表明:地震动绕z轴扭转分量对隔震支座的影响很小,以后还需针对不同的结构类型和地震动做更多的研究。
This paper introduces the theory of obtaining seismic torsion acceleration,and gains torsion acceleration component of LIMON COSTA RICA seismic motion by turning around z-axis in Matlab program.A 12-story base-isolation structure is given time history analysis by using ANSYS software,and by inputting LIMON COSTA RICA seismic motion torsion acceleration component and translation acceleration.The results show that torsion acceleration component in z-axis has little impact on isolation bearings.It needs to do more studies on the different structures and earthquake motions.
