摘　　要：格栅管式双钢板混凝土剪力墙具备较高承载能力、良好延性和耗能能力,在高层建筑中具有良好应用前景。为了进一步研究格栅管式双钢板混凝土剪力墙的抗震性能,文章建立ABAQUS有限元分析模型,对格栅管式双钢板混凝土剪力墙进行抗震性能影响参数研究。结果表明:(1)格栅管式双钢板与管内混凝土协同工作,外侧双钢板对管内混凝土提供三向约束,管内混凝土的强度和延性大幅度提高;(2)在实际工程中,建议轴压比控制在0.6以内,建议中部腔体长宽比宜取1.4~1.8,端部腔体长宽比宜取1.0~1.4;(3)低剪跨比1.47时,格栅管式双钢板混凝土剪力墙也有良好的抗震延性。Grid tubular double steel plate concrete shear wall has high bearing capacity,good ductility and energy dissipation capacity,and has a good application prospect in high-rise buildings.In order to further study the seismic performance of grid tubular double steel plate concrete shear wall,ABAQUS finite element analysis model is established to study the influencing parameters of seismic performance of grid tubular double steel plate concrete shear wall.The results show that:1)the grid tubular double steel plates work together with the concrete in the pipe,the outer double steel plates provide three-dimensional constraints on the concrete in the pipe,and the strength and ductility of the concrete in the pipe are greatly improved;2)In practical engineering,it is suggested that the axial compression ratio should be controlled within 0.6,the length width ratio of the middle cavity should be 1.4~1.8,and the length width ratio of the end cavity should be 1.0~1.4;3)When the shear span ratio is 1.47,the grid tubular double steel plate concrete shear wall also has good seismic ductility.
