| 摘 要： | 文章针对海洋平台构件常见的腐蚀损伤(均匀腐蚀及局部腐蚀)和碰弯损伤，介绍了它们的等效刚度计算方法。在此基础上，开发了海洋平台损伤构件等效刚度计算软件模块。就损伤构件等效刚度计算以及使用大型通用有限元软件ANSYS对平台进行整体分析，文章提出了一种新方法，即用ANSYS的MATRIX27单元代替损伤构件单元。最后设计了2个算例，验证了等效刚度计算的正确性和这种新方法的可行性。

| Abstract: | The paper presents a method of calculating the equivalent stiffness of damaged members of offshore platform, on which a computer program designed for equivalent stiffness calculation is based. A new method is introduced for applying stiffness calculation to analysis of platform. Finally, two examples are designed to verify the new method. |
