【摘要】 基于6个不同设计参数保温模块单排配筋再生混凝土剪力墙低周反复荷载试验,进行了该类剪力墙的弹塑性有限元分析,分析结果与试验结果吻合较好。分析了不同再生混凝土强度等级、不同孔洞形状和边框参数对保温模块单排配筋再生混凝土剪力墙的影响。研究表明:再生混凝土强度对提高剪力墙的承载能力具有一定贡献;保温模块芯肋削弱了剪力墙的承载力及刚度,提高了墙体的变形能力;芯肋形状对剪力墙的承载力影响不大;边框柱对剪力墙承载力有重要贡献。更多还原

【Abstract】 The elastic—plastic finite element analysis of the recycled aggregate concrete shear wall with single row reinforcements adhered to insulation blocks is carried out based on low—cycle repeated loading test of the six shear walls with different design parameters.The elastic — plastic finite element analysis results are in good agreement with the experimental results.The influence of recycled concrete strength,shape of holes and boundary frame parameters on the recycled concrete shear wall with single row reinforcements are analyzed.Research results shows that:the strength of the recycled concrete has made certain contribution to improve shear wall bearing capacity;core ribs of heat insulation blocks weaken the shear wall bearing capacity and stiffness,but can improve the deformation capacity of the wall;core rib shape of has little effect on the shear wall bearing capacity;the parameters of the frame column has great contribution to shear wall bearing capacity.更多还原
