摘　　要：针对型钢高强度混凝土剪力墙-梁节点中梁钢筋难以锚入剪力墙中的问题,提出通过调整混凝土梁钢筋排布方式,配合使用锚固板,将梁钢筋锚入节点的优化方案。建立ABAQUS有限元模型,对比分析优化前后梁钢筋在设计荷载工况下的受力,验证了优化方案的可行性。对比分析结果表明:优化后方案中的型钢、钢筋在设计荷载工况下的应力均低于屈服应力,处于弹性工作状态,优化方案达到了既能使混凝土梁钢筋锚入节点,又能减少型钢穿孔的目的。Aiming at the problem that it is difficult to anchor the beam steel reinforcement into the shear wall in the steel reinforced high strength concrete shear wall beam joint,the optimization scheme of anchoring the beam reinforcement into the joint by adjusting the arrangement of the concrete beam steel reinforcement and using the anchor plate is put forward.The ABAQUS finite element model is established,and the stress of the beam steel reinforcement before and after optimization under the design load condition is compared and analyzed,and the feasibility of the optimization scheme is verified.The results of comparative analysis show that,the stress of the section steel and steel reinforcement in the optimized scheme is lower than the yield stress under the design load condition,and they are in the elastic working state.The optimization scheme can not only make the steel reinforcement of the concrete beam anchor into the joint,but also reduce the section steel perforation.
