摘要
通过有限元系统分析矩形钢管焊接空心球节点在轴力作用下的受力性能,建立采用壳单元的有限元模型,对轴力作用下的矩形钢管焊接空心球节点进行弹性有限元分析,给出轴力作用下矩形钢管焊接空心球节点的应力分布规律,并对它的力学性能进行分析.
Finite element analysis is carried out to investigate the performance of welded hollow spherical connected with rectangular steel tubes under axial force.Elastic finite element analysis of these joint under axial force adopting finite element model of solid unit is conducted.And then the distribution rule of the stress of these joints is provided and their mechanical performance is analyzed.
