研究岛式上层建筑总强度的载荷原因及加载途径，基于有限元理论、船体总强度理论提出一种新的岛式上层建筑强度计算方法。该方法良好适应当前船体设计计算现状，可有效利用船舶设计计算过程中的船体总强度计算结果，可克服上层建筑传统计算方法存在的缺点、满足结构优化设计的要求。分别使用有限条法和本文方法对某船上层建筑结构总强度进行计算，发现有限条法的计算结果偏小。
Research on the load reason and loading ways of the overall strength of the island structure. Based on the theory of finite element and the theory of hull strength,proposed a new method for calculating the strength of island structure. The method is well suited to the current situation of the hull strength. Which can effectively used the calculation results of the hull strength in the calculation process of the ship, and overcame the shortcomings of the traditional calculation method of the overall strength of the superstructure and meet the requirements of structural optimization design. The finite strip method and the finite element method were used to calculate the overall strength of the superstructure of a ship, and finally found that the results of finite strip method are smaller.
