| Abstract: | In this paper, several items were discusses during marine structure FEA was executed based limit strength and progressive collapse analysis. Elastic analysis theory and plastic consideration method were put forth. At the same time, The controlling method and several main questions in FEA executing procedure were discussed to give solid foundation for improving the reliability of analysis. |
