摘要
在考虑地震动竖向扭转分量的情况下,对双向偏心的框架结构进行弹塑性地震反应分析,比较分析双向偏心框架结构在多维地震动作用下的平动反应、扭转反应等,进而得到关于结构扭转效应的动力特征和规律,为结构设计人员提供一些理论依据。
In this paper,in considering seismic vertical torsion component,the analysis of the elastic-plastic seismic response of bidirectional eccentric frame structure was done,comparative analysis of the parallel reaction and torsional response of the bidirectional eccentric frame structure under the multi-dimensional seismic response was carried out,then dynamic characteristics and rules of the torsional effect were got,and provided some theoretical basis for the designer of structure.
