T、Y型方圆相贯管节点极限承载力有限元分析
Finite element analysis on the tubular T、Y-joints’ ultimate strength
【摘要】 采用四节点壳单元对T、Y型方圆直接相贯管节点进行非线性分析,旨在研究此类节点的受力性能和塑性区扩展过程,分析讨论节点破坏机理并获得节点极限承载力随其节点几何参数变化的规律。提出节点加强方案。
【Abstract】 In the paper , nonlinear finite element analysis on the tubular T?Yjoints (square chords and circular braces) is carried out . A fournodeshell element is employed to stimulate the joints in the analysis. The results show the joint failure mechanism and plasticity spreading with loading. The effect of various geometric parameters of the joint on behavior and ultimate strength are investigated theoretically. Some strengthening solution are suggested for construction projects.
