摘　　要：基于ABAQUS软件,对新型内置纤维增强复材管的钢管混凝土边框剪力墙进行不同荷载作用下的数值模拟,利用数值分析结果,将该新型剪力墙与双钢管混凝土边框剪力墙和普通钢管混凝土边框剪力墙对比,对该新型剪力墙的力学性能和抗震性能进行分析研究。研究结果表明:内置FRP管的钢管混凝土边框剪力墙的承载能力、延性、滞回性能和耗能能力等方面都明显优于其他两种组合剪力墙,具有更优良的抗震性能。In this study,a numerical study was carried out using ABAQUS software capable of doing nonlinear analysis to investigate the performance of new composite shear wall with CFST incorporating FRP-confined concrete core（ referred to as new composite wall for brevity）. Based on the numerical results obtained from the study,a comparison of performance was made between the new composite wall with the other two walls： shear wall with concrete filled double-skin tubes（ CFDT） columns and ordinary shear wall with CFST columns. Based on the comparison,the mechanical and seismic performances of the shear wall with CFST columns incorporating FRPconfined concrete core were analyzed and discussed. The results showed that the bearing capacity, ductility,hysteretic behavior and energy dissipation capacity of the shear wall with CFST columns incorporating FRP-confined concrete core were obviously superior to those of the other two composite shear walls,and thus it had much better seismic performance.
