Beam deflection, column buckling, welds and padeyes, with the section properties and the code or textbook method named on the page.

• Beam deflection and bending stressMaximum bending moment, bending stress, deflection and reactions for simply supported, cantilever and fixed beams with standard sections.
• Column buckling (Euler and Johnson)Critical buckling load of a compression member by Euler or the Johnson parabola, with end-condition factors, slenderness, allowable load and utilisation.
• Fillet weld strengthThroat area and design resistance of fillet welds under shear, tension and bending (Eurocode 3 directional and simplified methods).
• Padeye design checkPlate geometry around the hole, bearing, and shear and bending of the shackle pin of a lifting padeye to EN 1993-1-8 pin connections.
• Stiffener with attached platingNeutral axis, moment of inertia and section moduli at the plate and the flange of a stiffener with its effective plate flange.
• Weld fatigue damage (DNV-RP-C203)Miner damage and fatigue life of a welded detail from a stress-range histogram on the DNV-RP-C203 S-N curves, with thickness effect and DFF.
