“…While Paik et al (2012) applied the design formula (analytical) method, this study focuses on the differences between the ISFEM (ALPS/HULL) (ALPS/HULL, 2012) and the design formula methods (modified Paik and Mansour method or modified P-M method) (Paik et al, 2013) in assessing the safety of damaged ship structures. The results from the two methods are compared to determine the most practical approach.…”

“…Recently, Paik et al (2012) proposed a new concept, the R-D diagram, for accurately evaluating the safety of damaged ships using the design formula method (Paik et al, 2013) to predict the residual ultimate longitudinal strength of ships damaged by grounding. The method is based on the presumed stress distribution of the mid-ship section (Hughes and Paik, 2010).…”

A simple analytical model to estimate the longitudinal strength of ship hulls in composite materials under buckling, material failure and ultimate collapse is presented in this paper. Ship hulls are regarded as assemblies of stiffened panels which idealized as group of plate-stiffener combinations. Ultimate strain of the platestiffener combination is predicted under buckling or material failure with composite beam-column theory. The effects of initial imperfection of ship hull and eccentricity of load are included. Corresponding longitudinal strengths of ship hull are derived in a straightforward method. A longitudinally framed ship hull made of symmetrically stacked unidirectional plies under sagging is analyzed. The results indicate that present analytical results have a good agreement with FEM method. The initial deflection of ship hull and eccentricity of load can dramatically reduce the bending capacity of ship hull. The proposed formulations provide a simple but useful tool for the longitudinal strength estimation in practical design.

“…Yao and Nikolov (1992) constructed a practical computer code for progressive collapse analysis utilising this method. Moreover, the analytical method for the ultimate strength calculation of the ship hull was proposed by Paik and Mansour (1995) and this method was modified so as to be more general (Paik et al 2013).…”

The objective of this study is to propose an analysis method of ultimate hull girder strength under combined bending and torsion. The hull girder is modelled by a series of thin-walled beam elements and the average stress-average strain relationship of plate and stiffened panel elements under axial loads considering the effect of shear stress is implemented in the beam elements. First, a torsional moment is applied to the beam model for a whole model within the elastic range. Then, the ultimate bending strength of cross-sections is calculated applying Smith's method to beam elements considering the warping and shear stresses. The proposed simplified method is applied to the progressive collapse tests of scale models under combined loads. On the other hand, nonlinear explicit finite element method (FEM) is adopted for the analysis of the test models. The effectiveness of the simplified method is discussed comparing with the results of experiments and FEM analysis.
