摘　　要：内置FRP管的钢管混凝土边框剪力墙由钢筋混凝土、钢管混凝土和FRP约束混凝土组合而成,具有优良的力学性能和抗震性能。结合拟静力试验结果,对该组合剪力墙的受力机理进行研究,并对钢管混凝土和内置FRP约束混凝土的应力状态进行分析和简化,从而建立内置FRP管的钢管混凝土边框剪力墙的极限承载力计算公式。通过与试验结果的对比分析,验证该承载力公式的正确性和适用性,为进一步的研究以及推广应用提供可靠的理论依据。Composite shear walls incorporating concrete-filled steel and FRP tubes as boundary elements are a new type of hybrid structural members and have excellent mechanical and seismic performance.Combined with the results of quasi-static tests,the stress mechanism of the composite shear wall was analyzed,and the stress states of concrete-filled steel tube and FRP-confined concrete were analyzed and simplified.Thus,the calculation formula of ultimate bearing capacity of composite shear walls was established.Through a comparison with the experimental results,the correctness and applicability of the bearing capacity formula were verified,which provides a reliable theoretical basis for further research and application.
