Abstract

Abstract

In order to investigate the rule of elasto-plastic torsional response of the eccentric frame-shear wall structure under earthquake action,a group of fine finite element models of actual frame-shear wall structure designed according to China code with different eccentricity were established for a comparative study in terms of their structural elasto-plastic seismic responses,such as the storey drift angle and torsional angle,distribution of plastic hinge,ductility coefficient,etc,using dynamic time-history analysis with many different seismic waves.The analysis results showed that the rule of elasto-plastic storey drift angle and interlayer torsional angle is consistent with the previous research using macroscopic model,and the storey drift angle satisfy the seismic requirements of code;the ductility demand of the rigid side elements is about 2~3 times large than that of the flexible side elements;the ductility demand of the rigid side elements of the frame-shear wall structure with rigid foundation assumption under artificial rare earthquake action is too large,which should be paid attention to.
