中文摘要：
为设计出安全、可靠的桁架式Spar平台结构，针对桁架式Spar平台的结构特点和受力特征，以平台结构整体的弯矩、剪力为控制内力确定控制荷载工况，并结合ABS规范对平台结构进行了强度校核。首先介绍了桁架式Spar平台结构强度校核的分析流程；然后建立了考虑系泊、立管系统的Spar平台耦合运动模型，并进行了平台水动力分析，确定了平台最不利荷载工况；最后基于准静态分析方法和局部精细化有限元模型，对最不利荷载工况下平台结构进行了强度分析，并根据规范对平台主体结构进行了强度校核。结果表明：平台关键连接部位应力水平很高，应力比都超过了0．9，评估结果可为类似平台结构的分析和强度设计提供参考。
英文摘要：
In order to design a safe and reliable Truss Spar platform, according to structural and mechanics characteristics of the Truss Spar platform, the control load conditions are determined by the control internal force which can be the platform structure＇s whole bending moment and shear force. And then, combined with ABS rules, the structural strength of platform is checked. The analysis process of the structural strength check was firstly introduced. Then, the model of the Spar platform coupled with the mooring and riser system was built, the hydrodynamic performance was analyzed and the worst load condition was confirmed. Finally, based on quasi-static analysis method and the finite element model with local refinement, the global structural strength analysis was completed under the worst load condition, and strength check was calculated in accordance with the rules. The results show that stress levels of the key connection parts of platform are quite high and its stress ratio has exceeded 0.9. The assessment results can be a reference for the analysis of similar platform structures and strength design.
