摘　　要：根据海洋平台结构管节点设计准则,自行开发了海洋平台管节点强度校核和可靠度分析软件,应用冲剪校核和名义应力校核法对渤海BZ28-1单点系泊海洋导管架平台结构管节点进行了强度校核,并用可靠度分析软件计算了管节点强度可靠度,找到了海洋平台的最不利的节点和工况组合,为合理设计海洋平台结构和现役平台结构的科学评估、检测、维护和修理提供了分析方法和理论依据。Strength check software and reliability analysis software of tubular joints in offshore platform structures are developed based on design principle of tubular joints. Punching shear and normal loads check methods are performed to check the strength of the tubular joints of BZ28-1 single point mooring offshore jacket platform.The reliability analysis software is applied to calculate the reliability of tubular joints. The worst tubular joints and load combination cases are found. The analysis method is provided for designing offshore platform structure reasonably and evaluating, detecting, maintaining and repairing offshore platform in service scientifically.
