【摘要】 T型钢连接根据几何参数的改变具有不同破坏模式和能量耗散的能力。利用ANSYS有限元分析软件建立了6不同构造尺寸的三维有限元模型,并对其进行轴向循环荷载作用下的有限元分析。在参数α’>1.0情况下,研究了翼缘板厚度、螺栓直径和螺栓中心距腹板表面距离参数变化对T型刚连接节点耗能能力的影响。分析结果表明:T型钢连接节点具有较强的塑性变形的能力;改变T型钢翼缘厚度、螺栓中心距离腹板表面距离和螺栓直径对T型钢连接的承载能力和T型钢连接节点的耗能能力均有显著地影响。更多还原

【Abstract】 T-stub connections display different failure modes and energy dissipation according to the change of geometrical parameters. In this paper,using ANSYS software build six 3- D FE models of different sizes of T-stub connections,and finite element simulation under axial cyclic loading was done. Under the parameter α’> 1. 0,It was studied the effects on their energy dissipation capacity due to changes in the geometric parameters,such as flange plate thickness,bolt diameter and the distance of bolts from the center to the edge of the web. The results showed that Tstub connections has high plastic deformation capacity,changing flange plate thickness,bolt diameter and the distance of bolts from the center to the edge of T-stub connections had greater impacts on their energy dissipation capacity and the bearing capacity.更多还原
