【摘要】 为了研究半刚性框架-波折钢板剪力墙结构的抗侧性能,基于ABAQUS有限元分析软件,建立内嵌墙板分别为横放波折钢板、竖放波折钢板两种不同形式的模型算例进行低周往复加载数值分析,变化框架节点刚度、墙板宽高比、柱轴压比等关键参数,对比研究了其滞回曲线、耗能能力、面外变形等性能规律。研究发现,半刚性框架—波折钢板墙能够减轻主构件的塑性损伤,具有与刚性框架—波折钢板墙接近的抗侧性能;当宽高比大于1.0时,采用竖放波折钢板墙的结构整体具有稳定的抗侧承载力、延性和耗能能力,对于宽高比等于或小于1.0的情况,横放波折钢板墙的抗侧性能较好。轴压比会显著降低半刚性框架—波折钢板剪力墙中竖放内嵌波折墙板、边缘框架的抗侧承载力,对横放内嵌波折墙板的抗侧性能影响不大。更多还原

【Abstract】 In order to study the lateral resistance performance of semi-rigid frame-corrugated steel plate shear wall structure,based on the finite element analysis software ABAQUS,two different types of model examples of horizontal corrugated steel plate and vertical corrugated steel plate were established for numerical analysis of low cycle reciprocating loading,and key parameters such as frame joint stiffness,wall panel width-to-height ratio and column axial compression ratio were changed.The hysteretic curve,energy dissipation capacity and out of plane deformation were compared and studied.It is found that the semi-rigid frame-corrugated steel plate wall can reduce the plastic damage of the main component,and has similar lateral stiffness and resistance as the rigid frame-corrugated steel plate wall.When the aspect ratio is greater than 1.0,the structure with vertical corrugated steel plate wall has stable lateral resistance,ductility and energy dissipation capacity as a whole.When the aspect ratio is equal to or less than 1.0,the lateral resistant performance of transverse corrugated steel plate wall is better.The axial compression ratio can significantly reduce the lateral resistance of vertical embedded corrugated wall panels and edge frames in semi-rigid frame-corrugated steel plate shear walls,but has little effect on the lateral resistant performance of horizontal embedded corrugated wall panels.更多还原
