摘要
为研究钢结构梁柱翼缘连接焊缝对侧板加强型节点发生断裂可能性的影响,在考虑焊接残余应力的基础上,对指定路径的断裂指标分布规律进行研究,并针对有无考虑焊接残余应力的两种节点所对应的开裂指标进行分析,最终认为梁柱翼缘连接焊缝对导致节点根部发生脆断的可能有一定影响。
In order to define the impact of weld on brittle fracture of side-plate reinforced joint , this paper studied the fracture criterion distribution features along different paths and analyzed rupture index characteristics according to the two models either with or without weld at the flange junctioning residual stress .Based on the above research , the results show that weld at the flange junction of beam and column residual stress has a certain influence on producing brittle fracture at the root of the joint .
