主管轴力对钻石鸟嘴式X型节点力学性能影响

摘要

运用ANSYS软件,对主管轴向力作用下的钻石鸟嘴式X型相贯节点的力学性能进行了非线性有限元研究,分析了主管轴力对节点力学性能的影响,得到了考虑主管轴力的节点承载力折减系数表达式。%The study adopts the ANSYS software to have the non-linear finite element research on the dynamic performance of diamond bird beak intersection X-joints under the axial stress of main pipes,analyzes the influence of the axial stress on the dynamic performance of the joints,and concludes the formula for loading reduction factors at the joints under the axial stress of main pipes.
