摘要
The inelastic seismic responses of shear-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 orthogonal earthquake excitations on inelastic displacement and ductility were studied respectively. Numerical results show that aforementioned factors influence the seismic responses of the buildings. The effect of the orthogonal input of ground motion is likely to be restricted to the moving status of eccentric elements.
