Ultimate Strength Envelope of a 10,000TEU Container Ship’s Global Hull Girder Subjected to Combined Vertical Bending, Horizontal Bending and Torsion

Abstract

Abstract To figure out the ultimate strength picture of the global hull girder of a 10,000TEU container ship subjected to combined vertical bending, horizontal bending and torsion, a simplified global hull girder of the chosen container ship is numerically modeled and a series of large deflection and elastoplastic nonlinear finite element analyses are conducted to obtain the ultimate strength envelope of the chosen container ship’s global hull girder subjected to combined vertical bending, horizontal bending and torsion. Based on the obtained numerical results, the equations that can quantify the ultimate strength envelope of the chosen container ship’s global hull girder subjected to combined loads are developed, which can be referred as one of the most important indexes to measure the safety performance of the chosen container ship under the most extreme loading conditions.
