【摘要】 在多腔式双钢板组合剪力墙低周反复水平荷载试验基础上,建立ABAQUS有限元模型,进行抗震试验的仿真模拟,重点模拟破坏形态和累计损伤状态。研究表明:管内填混凝土受到外侧双钢板的约束,其强度和延性得到改善;极限破坏状态时候,呈现弯曲破坏特征,端部槽钢撕裂破坏,管内填混凝土没有被压碎;多腔式双钢板组合剪力墙的累计损伤不断发展,脚部塑性区发展充分,具有良好的抗震耗能能力;多腔式双钢板组合剪力墙破坏时,水平位移角高达1/41,可保证钢管混凝土框架作为抗震二道防线可以有效地参与工作。更多还原

【Abstract】 Based on the low-cycle reversed horizontal load test of multiple-cavity double steel plate composite shear wall,the ABAQUS finite element model is established to simulate the seismic test,focusing on the failure mode and cumulative damage state.The results show that the strength and ductility of the concrete filled in the pipe are improved due to the restraint of the outer double steel plates;In the ultimate failure state,it shows the characteristics of bending failure,the end U-steel is torn,and the concrete filled in the pipe is not crushed;The cumulative damage of multiple-cavity double steel plate composite shear wall is developing continuously,the plastic zone of the foot is fully developed,and it has good seismic energy dissipation capacity;When the multiple-cavity double steel plate composite shear wall is damaged,the horizontal displacement angle is as high as 1/41,which can ensure that the concrete-filled steel tubular frame can effectively participate in the work as the second line of defense against earthquake.更多还原
