摘要
针对空间网格结构工程中钢管相贯节点间隙可能出现的大间隙超偏差问题,进行试验研究,结果表明:钢管相贯节点大间隙焊缝对试件承载力影响较小,对试件延性影响较大。
An experimental research was carried out on the large clearance super deviation of an intersection node of round steel tubes for space grid structures;and the result shows that the large clearance weld of the intersection node of the steel tube has a little influence on bearing capacity of specimens,but has a greater influence on specimens ductility.
