摘　　要：采用有限元软件ANSYS对某观光塔结构中一个斜交网格结构空间相贯焊接节点在多种荷载工况下的受力性能进行了全面的分析,并与规范计算值进行比较。考察了不同壁厚、有无加设竖向或横向拼接板等多种因素对节点的极限承载力的影响及达到极限承载力时的破坏特征,进而对节点性能做出了综合评价。The bearing capacity of a welded spatial steel tubular joint used in diagonal crossing grid structure of a tower under multiple load cases is comprehensive analyzed by ANSYS and compared with code for design values. The influence of several factors as different thickness, whether vertical or horizontal stitching additional partitions on joint bearing capacity are taken into account. The disfeature reaching the limits of bearing capacity of the joint is found, and the general estimate of the joint＇s performance is achieved .
