Sažetak
This technical note firstly reminds on the idealized elastic-plastic modeling of the ultimate strength of structural elements. Next it reviews the ultimate strength assessment procedures for the ship’s hull supported by the Common Structural Rules (CSR) and by the American Petroleum Institute (API) standards. In the continuation the study compares the idealized ultimate strength assessments according to the flow stress approach recommended by the API-579 standards and the minimal yield strength approach as it is adopted by the CSR. At the end, the two approaches are separately applied to recently build five tankers and three bulk carriers following the simplified iterative-incremental method for ultimate strength assessment of the ship hull girder implemented in the program MARS. The paper indicated the differences in participation of buckling and plastic yielding in the total ultimate bending strength of the hull girder. The conclusion is that there are significant potential reserves in the hull girder ultimate strength with respect to the various assessments based on the idealized computational procedure recommended by the CSR.
