摘　　要：为了获得顶底角钢连接中带肋角钢的荷载-位移关系,采用有限元软件ANSYS进行模拟分析.首先建立简化的有限元模型,然后分别设置角钢与柱之间、螺栓与角钢、柱之间的接触关系,最后对模型进行单调加载,获得角钢的荷载-位移关系.结果表明:有限元模拟结果与理论分析结果具有高度的一致性;单肋、双肋角钢的屈服荷载、初始刚度分别约为无肋角钢的2倍、3倍;设置加劲肋可有效改善角钢的力学性能.In order to obtain the load-displacement relationship of the ribbed steel angle of the top-and-seat angle connections, ANSYS software was employed to simulate it. First, the simplified finite element model was established. Second, the contact relationship between the steel angle, high strength bolt and column component was set up. Last, the load-displacement relationship of the ribbed steel angle was obtained by applying monotonic loading to the model. The results were presented： the finite element simulation results are consist with theoretical analysis results;the yield toad and initial stiffness of single rib, double rib steel angle are approximately 2 times, 3 times of common angle re- spectively ; the mechanical properties of steel angle can be effectively improved by the stiffener.
