摘要
采用ABAQUS软件建立有限元模型,分析了T型弯曲翼缘开孔板连接件的抗剪性能和极限抗剪承载力影响因素.研究了连接件的荷载-滑移曲线特性、不同网格尺寸对模拟的极限抗剪承载力的影响、不同参数对抗剪承载力的影响、以及不同参数下极限承载力变化趋势的拟合公式.研究结果表明,T型弯曲翼缘开孔板连接件的荷载-滑移曲线可以划分为弹性阶段、弹塑性阶段和破坏阶段;提高混凝土强度、增加开孔板板厚、减小开孔直径和增加翼缘宽度可以提高开孔板连接件的极限抗剪承载力.
In this paper,the finite element model is established by using ABAQUS.The shear behavior of the connector of the T-Shaped flange perfobond connector and influence factor of the ultimate shear capacity are analyzed.The load-slip curve characteristics of the connector,the influence of the mesh size on the simulated ultimate shear capacity,the influence of different parameters on the shear bearing capacity,and the fitting of the ultimate bearing capacity under different parameters are studied.The results show that the load-slip curve of the T-shaped flange perfobond connector can be divided into elastic stage,the elastic-plastic stage and the failure stage.The increase of concrete strength,the increase of the thickness of the perforated plate,the decrease of the opening diameter and the increase of the flange width can increase the ultimate shear capacity of the T-shaped flange perfobond connector.
