A return period based plastic design approach for ice loaded side-shell/bow structures
Journal article, 2009

Based on the design ice load that corresponds to a certain return period, a practical approach for designing the frames behind the side-shell or the bow of a ship subject to ice loading is proposed. Four typical types of section profiles have been selected for modelling and numerical analysis. Nonlinear finite element analyses that involve both the geometric and material nonlinearity were performed. From the analyses, the relationships between the loads and the beam’s cross-section properties were obtained for different permanent set requirements. These relationships were then used for finding the section modulus from which the cross-section of the beam can be decided. Finally, a design example is presented for illustration.
