地震动转动分量研究综述

Review of Research on Ground Motion Rotational Component

随着经济社会的发展及地震工程研究的深入,地震动转动分量及其响应研究开始受到关注,国内外学者对此进行了大量的研究。结合国内外学者的相关研究成果,梳理了地震动转动分量提取方法及地震动转动分量下工程结构响应研究进展。同时指出了目前地震动转动分量研究中存在的问题,以及今后的研究方向。

With the development of economic society and the deepening of earthquake engineering research,earthquake rotational component and its response research began to receive attention.Domestic and foreign scholars have done a lot of research on this.Based on the relative research results of domestic and foreign scholars,the extraction method of ground motion rotational component and response of engineering structure under rotational ground motion were intreduced.At the same time,the problems existing in the current research on the ground motion rotational component and the future research direction were pointed out.
