摘要
对两个足尺钢结构栓焊节点的火灾行为进行了试验研究,通过对该类型节点在火灾下的破坏现象和破坏特征的观察分析,得出了栓焊节点在火灾下的破坏规律:接焊缝是抗火的薄弱环节,节点区域柱子的翼缘发生屈曲使节点在火灾下发生较大转角,从而为节点的抗火设计提供依据。
Two full-scale experiments have been carried out on fire-resistance of welded flange-bolted web connections with rib stiffener and without rib stiffener. The phenomena and characteristics of failure were described. From the experiment, the failure modes have been obtained. Weld is the weakness of the joint in fire and flexure of column flange in the region of connection is the main factor to make joint rotate largely, which can provide more bases for the fireresistance design of this kind of joints.
