Research on the Inelastic Seismic Responses of Shear-Type Multistorey Buildings With Regular Asymmetry

对多层剪切型的均匀偏心结构进行弹性地震反应分析 ,研究了基本平动周期、平扭频率比、偏心率、地震动强度、非偏心向地震动等对结构的弹塑性位移和构件延性反应的影响· 研究表明 :上述因素对结构的位移和延性反应有较大的影响 。

The inelastic seismic responses of she ar -type multistorey buildings with regular asymmetry were analyzed. The effects of the fundamental lateral period, the fundamental frequency ratio of translational to torsional, the eccentric ratio, earthquake intensity and orthog onal earthquake excitations on inelastic displacement and ductility were studied respectively. Numerical results show that aforementioned factors influence the s eismic responses of the buildings. The effect of the orthogonalinput of ground m otion is likely to be restricted to the moving status of eccentric elements.
