Abstract

In order to examine the effect of initial imperfections and lateral loads on the hull girder ultimate strength of intact and damaged ships, a series of nonlinear calculation is performed using FE analysis code, LSDYNA. In addition, the hull girder ultimate strength of intact and damaged ships is calculated utilizing the simplified calculation program, which is developed by authors and based on the Smith's method, and the reduction rate of hull girder ultimate strength is also investigated. Furthermore, to examine the accuracy of this simplified calculation program, the calculation results are compared with the results obtained from FE analysis.
