摘要:为了研究单排套筒连接的预制装配式混凝土剪力墙的应力、承载力以及变形能力的变化规律,利用ABAQUS有限元分析软件,对不同材料强度、轴压比和配筋率的预制装配式混凝土剪力墙进行水平单调加载,并对其受力性能进行分析。结果表明:随着轴压比的增大,剪力墙刚度提高,承载力先增大、后下降,延性性能逐渐变差;随着混凝土强度等级的提高,剪力墙最大承载力提高,提高的幅度逐渐减小;随着钢筋强度的增加,剪力墙承载力略有增加,不过效果并不明显;随着配筋率的增大,剪力墙最大承载力略有增加,效果并不显著,但可以提高构件的延性。

Abstract:In order to study stress state, load capacity and deformation changes of concrete shear wall with single sleeve connection, the mechanical performance of precast concrete shear walls with different axial compression ratios, reinforcement ratios and material strength under horizontal monotonic loading were analyzed by using the finite element software ABAQUS. The results show that with the increasing of axial compression ratio, the stiffness of shear wall is increased, the ultimate strength capacity is firstly increased and then declined, and ductility performance becomes worse. With the increasing of concrete strength grade, the ultimate strength capacity of shear wall is increased, however the increasing range declines. The strength capacity of shear wall is slightly increased with the increase of steel strength. The ultimate strength capacity of shear wall is slightly increased with the increase of reinforcement ratio, however the ductility of shear wall is significantly improved.
