【摘要】 对刚度偏心结构和质量偏心结构的地震响应作了详细深入的分析。建立了单层偏心结构在地震作用下的平扭耦联运动方程,并采用Rayleigh阻尼,应用时程分析法,对结构进行线弹性分析,解出在不同偏心率时结构模型的动力特性和地震反应,最后得出一些有用的结论,可为结构地震扭转效应的工程计算和设计提供参考。更多还原

【Abstract】 Detailed and deep analysis to seismic response of stiffness eccentric structure and quality eccentric structure has been made in the paper. The momentum differentiating equation of coupling between the translation and torsion of single layer of asymmetric structure under earthquake was established. By adopting Rayleigh’s damping model and using time-history analysis(Wilson-? Method),the linear elastic analysis of the structure was made,and the earthquake response and dynamic characteristics of the structure model were calculated under different asymmetric rates.Finally,the article draws some valuable conclusions,which can supply references to engineering calculation and design of structural torsional response undere arthquake.更多还原
