摘要
采用ANSYS结构分析程序的四节点板壳单元对T ,Y型方主管、圆支管相贯节点进行了弹塑性大挠度分析 ,研究了管节点的受力性能和塑性区扩展过程 ,揭示了节点的破坏机理和破坏形式 ,获得了其极限承载力及其随节点几何参数的变化规律 。
An inelastic large deflection finite element is used to study the behavior of the tubular T/Y joints(square chords and circular braces).A four node shell element in ANSYS is employed to simulate the joints in the analysis.The effect of various geometric parameters of the joint on its behavior and ultimate strength is investigated theoretically.Numerical studies show the joint failure mechanisms and plasticity spread with loading.Some useful conclusions are conducted,which are very helpful to the design of such joints as well as to the form of relevant design code.
