摘　　要：本文利用层单元模型,建立了基于层剪力-扭矩等效屈服EYST面概念的求解多层偏心结构体系双水平向地震动作用下平扭耦联非线性地震反应的简化算法,并讨论了控制偏心结构非线性扭转反应的相关结构参数;通过数值分析,初步验证了该简化方法的实用性和可靠性。Based on the concept of the equivalent yieldied base sheartorque surface, using the story element model, this paper developed a kind of simplified approach for evaluation of the seismic nonlinear lateraltorsional coupling effects of multistory asymmetric building structures. Structural parameters to control the nonlinear seismic performance of asymmetric systems are discussed here. The practicability and reliability of this approach is also verified roughly by the numerical case study.
