摘要

摘要: 采用ABAQUS软件建立有限元模型，模拟开孔板连接件推出试验，研究贯穿钢筋对开孔板连接件抗剪承载力的影响。研究结果表明：模拟的推出试验结果与实际试验结果吻合较好，能够反映开孔板连接件的真实受力情况，贯穿钢筋的屈服强度和直径对开孔板连接件极限抗剪承载力有显著的影响，开孔板连接件的极限抗剪承载力随着贯穿钢筋屈服强度和直径的增加而线性增加；贯穿钢筋长度对开孔板连接件极限抗剪承载力影响不大，贯穿钢筋在开孔中不同位置对开孔板连接件抗剪承载力影响较小。根据研究结果给出了开孔板连接件的极限抗剪承载力与钢筋屈服强度、直径和长度的关系表达式。

Abstract: The finite element model was established by using ABAQUS software to simulate push-out test of perfobond rib shear connector. The influence of perforated rebar on the shear capacity of perfobond rib shear connector was studied. The results showed that the results of the nonlinear finite element method calculation agreed well with the experimental results. The finite element method could simulate true force bearing behavior of perfobond rib shear connector. The yield strength and diameter of rebar had significant influence on the ultimate shear strength of perfobond rib shear connector. With the increase of yield strength and diameter of the rebar, the shear capacity of perfobond rib shear connector also increased linearly. The length and position of perforated rebar had little influence on the ultimate shear capacity of perfobond rib shear connector. Based on the research results, the relationships between shear capacity and yield strength, diameter and length of perforated rebar were presented.
