Abstract

This study presents the structural behaviour of catamaran hulls under hogging and sagging conditions. A comprehensive nonlinear finite element analysis is carried out using ABAQUS software to simulate the structural behaviour of the hull across various configurations. The investigation evaluates the influence of span-to-length (S/L) ratios, frame spacing, and hull lengths on bending moment and tensile strength characteristics. The results reveal that increasing frame spacing reduces the catamaran's structural rigidity, while higher S-to-L ratios or extended lengths significantly enhance ultimate tensile strength and bending moment due to the larger bridge area and increased structural spacing. These findings highlight essential design trade-offs, providing valuable insights for optimising catamaran hull performance in terms of safety, structural integrity, and operational efficiency. This work contributes to advancing the design and analysis of high-performance catamarans, ensuring reliability under various structural conditions.
