Abstract

In the Harmonized Common Structural Rules, which comes into force on 1st July 2015, the partial safety factor for the vertical hull girder ultimate bending capacity, γDB, will be introduced for bulk carriers and oil tankers to take account the effect of double bottom bending under lateral loading. In this paper, in order to examine the effect of lateral loads on the hull girder ultimate strength of bulk carriers, a series of nonlinear calculation is performed using the finite element analysis code, LS-DYNA. In addition, the hull girder ultimate strength is also calculated utilizing the simplified calculation program based on the Common Structural Rules for Bulk Carriers, which is a kind of the Smith’s method. The calculation results obtained by this simplified method are compared with FEA results to verify the validity of γDB.
