Sažetak
This paper starts with a review of longitudinal strength methodology and of rule based procedures for ultimate longitudinal ship hull strength assessment. The particular emphasize is on IACS Common Structural Rules for tankers and bulk carriers. Typical recently built tankers and bulk-carriers are subjected to longitudinal strength analysis. The research proceeds with recalculation of elastic, fully plastic and ultimate bending moments for five tankers and three bulk carriers. The ship section modulus and longitudinal strength recalculations apply the commonly adopted method for working bending moments and the Smith method for ultimate bending moments. The paper at the end tabulates the results of calculations with respect to principal ship data, working stresses, sectional properties, elastic and plastic section modulus, working and ultimate bending moment in sagging and hogging conditions, shape factors and safety factors. The conclusion brings forward how the working and ultimate conditions are mutually related and recommends ranges of values for relations among elastic, plastic and ultimate bending moments.
