Scope: doubly symmetric rolled I/H sections, class 1–3, flexural and lateral-torsional buckling (general case), conservative linear N+M interaction (EC3 Annex A/B not implemented); properties computed from catalogue dimensions and should be compared with the manufacturer's tables. Results are an aid only and must be verified by a qualified, licensed engineer before use. National Annex presets are recommended values and must be checked against the official documents.
