摘要:

摘要:对1榀单跨2层1/3比例的方钢管混凝土框架竖向加劲薄钢板剪力墙进行了低周往复荷载试验，研究了方钢管混凝土框架竖向加劲薄钢板剪力墙的抗震性能利用有限元软件ABAQUS对其进行了非线性数值分析，并对比分析了数值分析结果与试验结果构建足尺模型研究了柱子轴压比、加劲肋数量、钢板墙高厚比和柱子柔度系数对方钢管混凝土框架竖向加劲薄钢板剪力墙滞回性能的影响结果表明：方钢管混凝土框架竖向加劲薄钢剪力板墙具有良好的抗震性能增大轴压比使结构的承载力和延性降低，但对滞回耗能和刚度退化影响较小；加劲肋数量对结构滞回耗能影响较大，但对承载力和刚度退化影响较小；高厚比和柱子柔度系数对结构的承载力、滞回耗能和刚度退化影响较大.

Abstract:

The low cyclic loading experiment was conducted on one 1/3 scaled one-bay two-story concrete-filled square steel tubular(CFSST) frame-thin steel plate shear walls(SPSWs) with vertical stiffeners. The seismic behavior of CFSST frame-thin SPSWs with vertical stiffeners was investigated. The nonlinear analytical analysis was conducted using the finite element package ABAQUS. The numerical results were compared with the experimental results to study the seismic behavior of the CFSST frame-thin SPSWs. The effects of axial compression ratio, number of stiffeners, ratio of height-to-thickness of the SPSWs and column flexibility factor on the hysteretic behavior of the CFSST frame-thin SPSWs with vertical stiffeners were studied by using the full size model. The results show that the CFSST frame-thin SPSWs with vertical stiffeners have good seismic behavior. The bearing capacity and ductility decrease with the increase of axial compression ratio, and the increase of axial compression ratio has little influence on energy dissipation and degradation of stiffness. The number of stiffener has considerable influence on hysteretic behavior, but it has little effect on the bearing capacity and stiffness degradation. The ratio of height-to-thickness of the SPSWs and column flexibility factor has great influence on the bearing capacity, energy dissipation and stiffness degradation
