摘要：为探究带窗洞的竖向分布钢筋不连接装配整体式剪力墙(SGBL装配整体式剪力墙)的受力性能，采用ABAQUS软件建立SGBL装配整体式剪力墙精细化有限元模型。有限元模型采用Cohesive接触和弹簧单元模拟预制墙板与后浇混凝土的拼缝，模拟所得荷载-位移曲线及破坏模式与文献中试验结果均吻合良好。在此基础上，对比了带窗洞SGBL装配整体式剪力墙与带窗洞现浇剪力墙受力性能的差异，并讨论了轴压比和洞口偏心等参数对带窗洞SGBL装配整体式剪力墙的承载力和刚度的影响。结果表明：通过适当增加边缘现浇段竖向钢筋，带窗洞SGBL装配整体式剪力墙可拥有等同带窗洞现浇剪力墙的承载力。此外，轴压比对两类开洞剪力墙受力性能影响均较小，洞口偏心对带窗洞SGBL装配整体式剪力墙的承载力影响较小，当洞口偏心率小于20%时，洞口偏心对刚度的影响小于8%。

Study on mechanical behavior of monolithic assembled concrete shear wall with non-connected vertical distribution reinforcement and window opening
Abstract: To investigate the mechanical behavior of monolithic assembled concrete shear wall with non-connected vertical distribution reinforcement(SGBL monolithic assembly shear wall) and window opening, a refined finite element model was developed in ABAQUS software. In the finite element model, Cohesive contact and spring connector were adopted for simulating the nonlinear behavior of the joints between precast wall panels and post-cast concrete. The load-displacement curves and the failure patterns obtained from the numerical analysis are in good agreement with the test results in literature. Based on the numerical model, the differences of mechanical behaviors of SGBL monolithic assembled shear wall with window opening and cast-in-situ shear wall with window opening, and the influence of parameters such as the axial compression ratio and the eccentricity of the window opening on the bearing capacity and rigidity of the SGBL monolithic assembled shear wall with window opening was analyzed. The result shows that by appropriately increasing the vertical reinforcement in the cast-in-situ boundary elements of the SGBL monolithic assembled shear wall with window opening, the bearing capacity of the SGBL monolithic assembled shear wall with window opening can be close to that of cast-in-situ shear wall. In addition, the axial compression ratio has little effect on the mechanical behaviors of the two types of shear wall with window opening, and the eccentricity of the opening had little effect on the bearing capacity of SGBL monolithic assembly shear wall with window opening. For an eccentricity of opening less than 20%, the influence on the lateral stiffness of SGBL monolithic assembled shear wall with window opening is less than 8%.
