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。
The elasto-plastic seismic response analysis of biaxially eccentric frame structure considering the vertical torsional component of ground motion is carried out. The translational reaction and torsional reaction of biaxial eccentric frame structure under multi-dimensional ground motions are compared and analyzed. Twist effect of the dynamic characteristics and laws for structural designers to provide some theoretical basis.
