Volex Labs / Calculations / Bolted moment connection design to Eurocode 3.

Bolted moment connection design to Eurocode 3.

Enter the beam, column and end-plate details, and Volex Anvil designs the moment connection by the EC3-1-8 component method: the tension resistance of each bolt row, the column-web and end-plate components, the connection moment resistance Mj,Rd and the vertical shear resistance Vj,Rd.

The connection is classified by strength and stiffness, following SCI P398 'Joints in Steel Construction: Moment-Resisting Joints', so the Mj,Rd matches the Green-Book approach used in UK practice.

Frequently asked

Does it use the component method?
Yes — the connection is built up from the EC3-1-8 §6.2 components (bolt rows, end plate, column web, flange) exactly as in SCI P398.
Does it classify the joint?
Yes — the joint is classified as nominally pinned, rigid or semi-rigid by stiffness, and full/partial strength by resistance.
Is it validated?
The moment and shear resistances are checked against SCI P398 — within 0.00%.
Free to use?
Yes — 10 calculations a month free; Pro (£29/month) adds unlimited runs and PDF calc sheets.
