| 摘 要： | 针对装配式剪力墙结合面的抗剪性能进行了数值模拟,研究了在不同混凝土强度下钢筋配筋率对结合面的抗剪承载力与荷载-位移曲线的影响。采用ABAQUS软件对装配式剪力墙的抗剪试验进行分析,验证了数值模型的准确性。结果表明,开裂荷载主要由混凝土强度控制,抗剪承载力主要由混凝土强度和配筋率大小决定。随着钢筋配筋率的增加结合面抗剪承载力也在增加,但延性减少。随着混凝土强度的增加结合面抗剪承载力和延性都在增加。

| Abstract: | A numerical simulation was performed on the shear resistance capacity of the interface of prefabricated shear wall. The effects of reinforcement ratio on the shear capacity and load-displacement curve of the interface were studied under different concrete strengths. The ABAQUS was used to analyze the shear test of prefabricated shear wall, and the accuracy of the numerical model was verified. The results show that the cracking load is mainly controlled by the strength of the concrete, and the shear capacity is mainly determined by theconcrete strength and reinforcement ratio. With the increase of reinforcement ratio, the shear resistance capacity of the interface is also increasing, but the ductility reduces. With the increase of concrete strength, the shear strength and ductility of theinterface are increasing. |
