摘要
采用四节点壳单元 ,对T、Y型方圆相贯管节点进行系统的数值模拟分析。考查相贯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几何参数变化的规律。提出节点加强方案 。
In this paper,nonlinear finite element analysis on the tubular T?Y-joints(square chords and circular braces)was carried out.A four-node-shell element was employed to stimulate the joints in the analysis.The results showed the joint failure mechanism and plasticity spread with loading.The effect of various geometric parameters of the joint on behavior and ultimate strength was investigated theoretically.Some strengthening solution are suggested for construction projects.
