Empirical Interaction Design Equations for the Ultimate Longitudinal Strength of Tankers, Bulk Carriers, Container Ships and General Cargo under Coupled Bending Moment

Ozgur Ozguc

Abstract


This research work presents the most extensive investigation of the hull girder ultimate strength under coupled bending moment. The main objective of the present study is to develop hull girder ultimate strength interaction relationships useful for the ship designs subject to a combination of vertical and horizontal bending moments, where the ordinary Smith’s method is employed using a developed computer code NEPTUNE with average stress-average strain relationship of element. The procedure adopted is applied to analyze on the seventeen ships such as nine tankers, five bulk carriers, one general cargo and two container vessels. The findings obtained are used to define interaction design equations proposed to account for the combination of the load effects. The interaction expressions proposed by other researchers are also addressed to discuss simple equations presented by this study.
