Longitudinal Strength (A011)

This license configuration allows the designer to estimate longitudinal weight distribution at an early stage of design, and then to refine it as the design develops.

Longitudinal distributions of shear force and bending moment may be derived from first principles, or modified in accordance with UK Ministry of Defence guidelines.

Critical sections of structure may be defined and analysed. The effectiveness of individual panels can be modified by the user.

Output provided includes overall section inertia and moduli about the deck and keel. Indications are given of the closeness of each panel to failure in tension and compression.

Soares:HULCOL
HULCOL is the ordinary Smith's method for the evaluation of the ultimate longitudinal strength of a hull girder applied using the average stress-average strain relationships based on a beam-column approach (Gordo and Guedes Soares 1996a). Influence of panel buckling is accounted introducing effective width after local buckling. Note: Smiths method means Progressive Collapse Analysis with Calculated - curves, that involves the use of numerical methods to determine the stress-strain curves of individual plate and stiffened plate elements, which are then integrated following the assumptions of simple beam theory in order to trace out the progressive collapse curve.
