HEA 320 — Cross-Section Classification & Resistances

This page shows pre-computed EN 1993-1-1 design values for the HEA 320 HEA section. The governing cross-section class is 2 (Class 2 — Compact), which determines whether the section may develop its full plastic moment capacity (Class 1–2) or is limited to the elastic moment (Class 3–4). Npl,Rd, Vpl,Rd, Mpl,Rd, and Mel,Rd are shown for all combinations of steel grade (S235 to S460) and national annex (EN γM0=1.00, NL γM0=1.10, DE γM0=1.05).
