摘　　要：基于钢材延性损伤和混凝土三向约束的塑性损伤的有限元分析模型,进行格栅管式双钢板组合剪力墙抗震试验仿真分析,开展试验结果与有限元结果对比分析。研究表明:格栅管式双钢板墙三向约束管内混凝土,管内混凝土强度和延性大幅度提高;管内混凝土保护了外侧双钢板,避免了外侧双钢板受压屈曲破坏,二者协同工作,优势互补,其极限水平位移角为1/35左右。Based on the finite element analysis model of ductile damage of steel and plastic damage of concrete with three constraints, the seismic test simulation analysis of grid tubular double steel plate composite shear wall was carried out, and the test results were compared with the finite element results. Research showed: The strength and ductility of the concrete in the tube are greatly improved by the three-way restraint of the concrete in the tube by the double steel plate wall with grid. The concrete in the pipe protects the lateral double steel plate to avoid the compression and buckling damage of the lateral double steel plate. The two work together with complementary advantages, and the limit horizontal displacement Angle is about 1/35.
