The evaluation of the maximum load-carrying capacity of structures is an essential issue in determining their safety. Only if the prediction of the ultimate strength is ensured, their probability of survival in extreme load conditions can be estimated. Particularly for safe dimensioning of ship structures, the determination of structural strength against buckling and yielding is required by Common Structural Rules (CSR). For ultimate strength calculations of ship structures, including ultimate hull girder capacity and ultimate strength of plates and stiffeners, the Finite Element Method (FEM) is a feasible tool. Despite the enormous development in computer technology, nonlinear finite element analyses (FEA) are still very time consuming and not easily to perform as well. Therefore the Idealized Structural Unit Method (ISUM) can be applied for collapse analysis of large structures.
