摘要
介绍了T形相贯节点抗弯性能试验的主要试验结果,并将试验结果与国内外学者的研究成果相比较。试验表明,试件在受弯作用下的破坏模式为节点处发生屈曲变形和支管处焊缝产生裂缝。从荷载—位移曲线说明T形相贯节点在一定条件下可以作为全刚性节点来进行设计,但在施工和加工过程中要保证焊缝的质量。
The main results of tests which are compared with the research of different dimestic and oversears academician are introduced in detail in the paper. The failure mode of test model was the local buckling failure of brace at joint, and the welding in the connection of the main tube and the branch tube is produced crack. From the curve of load - displacement, the T - joints can be referred to as full rigid joints, and their bending capacities can assure the strength of the members connected under certain limitations, however, the quality of welding should be guaranteeed in the procedure of construction and production.
