摘要：The modal and response spectrum of steel frame-composite shear walls are analyzed by ANSYS; the effects of joint stiffness on the natural vibration characteristic and dynamic performance under the frequent earthquake are studied. The results show that with joint stiffness increasing, the natural vibration period and drift decrease, whereas the base shear increases. This phenomena is significant when the joint is in the semi-rigid range. With same joint stiffness, the composite shear wall has better performance than steel plate shear wall when subjected to frequent earthquake. In the steel frame with composite infill wall structure, effects of joint stiffness on dynamic characteristics are not obvious, thus using semi-rigid joints is more reasonable for economical consideration.
