[摘要] 在考虑地震动竖向扭转分量的情况下，对单向偏心的框架结构进行弹塑性地震反应分析，比较分析四种偏心率的单向偏心框架结构在多维地震动作用下的扭转反应，进而得到关于结构扭转效应的动力特征和规律。

Abstract: Considering seismic vertical torsion component case, elastic plastic seismic response analysis of the unidirectional eccentric frame structure was done. Torsional responses of four eccentricity unilateral eccentric frame structures under the multi-dimensional seismic were compared. And then the dynamic characteristics and laws of torsion effect about the structure were got.

Keywords: seismic; unidirectional eccentric, torsion reaction
