摘　　要：为对支柱连接节点的极限状态与可靠性进行研究,建立大量支柱连接节点有限元模型,分析构件尺寸对该结构极限状态下失效模式和承载能力的影响,并通过对有限元模型计算结果进行非线性回归分析,获得考虑重要构件尺寸的结构极限承载力计算公式。在此基础上,利用上述公式建立支柱连接节点极限状态函数,形成该结构可靠性分析流程,最后通过算例对可靠性分析流程的适用性进行验证。研究结果可以对豪华邮轮支柱连接节点设计提供一定参考。In order to study the limit state and reliability of column connection joints,a large number of finite element models of column connection joints are established in this paper,and the influence of member size on the failure mode and bearing capacity of the structure in the limit state is analyzed.Through nonlinear regression analysis of the calculation results of the finite element model,the formula for calculating the ultimate bearing capacity of the structure considering the size of important members is obtained.On this basis,the limit state function of the column connection node is established by using the above formula to form the reliability analysis process of the structure.Finally,the applicability of the reliability analysis process is verified by an example.The research results can provide a certain degree of reference for the design of connection nodes of luxury cruise ship pillars.
