摘要
以某海上多功能工作平台的典型管节点为研究对象,分别采用模型试验、数值仿真和规范计算3种方法得到了平台管节点在轴力作用下的应力集中系数.在此基础上,对3种用于海洋平台管节点应力集中系数的分析方法进行了评价.
Taken the typical tubular joints of a multi-purpose jack-up platform as the research object, the stress concentration factors（SCF） of the tubular-joints under axial loading were obtained through the methods of modal test, numerical simulation and standard calculation. On that basis, the evalua- tion of three methods which used to analyze the stress concentration factors（SCF） of the tubular joints for offshore platform were given. Meanwhile, the research conclusions can be used to guide the struc- tural design and life evaluation of similar offshore jack-up platforms.
