Understanding LTB is essential for any steel beam design. We cover the key parameters, the Eurocode 3 reduction factor χ_LT, and how to choose the right section to minimise LTB risk.

IPE, HEA and HEB beams are all I-sections, but they behave very differently in practice. This article compares section efficiency, weight, and application suitability across the three families.

Selecting the correct steel grade affects cost, weldability, and safety margin. We compare the most common European and American grades with yield strength, ultimate tensile strength, and typical applications.

The choice between bolted and welded connections has major implications for fabrication cost, inspection, fatigue life, and site erection. This guide helps you make the right call on your next project.

Section classification determines whether a steel section reaches its plastic moment capacity before local buckling occurs. Learn how to classify any section for bending, compression, and combined loading.

Structural hollow sections offer high torsional stiffness, clean aesthetics, and excellent compression performance. This article covers when to choose SHS, RHS, or CHS and how to select the right size.

Fixed steel jacket platforms — environmental loading, structural configuration, API RP 2A design provisions, pile foundations, corrosion protection and fatigue analysis. Covers Efthymiou SCF equations and DNV-RP-B401 cathodic protection.

Offshore pile foundation design: axial capacity using API RP 2GEO (alpha and beta methods), p-y curves for lateral loading, grouted connections, WEAP driveability analysis, and pile group effects.

Wave load analysis for offshore structures: Morison equation (drag and inertia forces), Airy wave theory, JONSWAP spectrum, current blockage factors, marine growth allowances and worked calculation examples.
