为了分析翼缘板加强型节点处各焊缝残余应力对节点断裂可能的影响,利用有限元软件ABAQUS对翼缘板加强型节点进行拟静力循环加载模拟,针对不同的应力路径,考虑不同焊缝的残余应力影响,对各项断裂指标进行对比和分析。研究表明,翼缘板加强型节点可以有效降低梁柱连接处的断裂可能,但翼缘加强板端部角焊缝位置附近发生断裂的可能性较大,在施焊过程中,应尽量避免此处的焊接缺陷生成。 In order to analyze the possible influence of the residual stress of each weld on the flange fracture of the flange plate, the finite element software ABAQUS is used to simulate the cyclic loading of the flange-reinforced joints. For different stress paths, The influence of residual stress on the fracture indicators for comparison and analysis. The results show that the flanged stiffened joint can effectively reduce the fracture of the beam-column joint, but there is a high probability of fracture near the fillet of the stiffener at the end of the stiffener. During the welding process, the joint should be avoided as much as possible Department of welding defects generated.
