摘要
为研究梁柱翼缘对接焊缝处裂纹对节点发生断裂可能性的影响,利用ANSYS有限元软件对携裂纹工作的普通节点、板式加强型节点进行模拟研究。通过对指定路径上断裂指标的分析定量讨论裂纹位置对节点断裂性能的影响。结果表明:相较于加强型节点而言,对接焊缝处裂纹对普通节点断裂影响显著;不同位置的裂纹对节点断裂性能的影响不同。
In order to study the effects of the crack at the butt-weld of beam-to-column flange on the possibility of fracture,the tradition connection and plate reinforced connection with cracks were simulated by ANSYS. The quantitative discussion on the effects of crack location on fracture behavior of beam-column joints was conducted by analysis of fracture index on the specified path. The results indicated that compared with the strengthened joints, cracks on the butt weld had a significant effect on fracture behavior of tradition connection; the effects of crack at different positions on the fracture behavior were different.
