Volex Labs / Calculations / Reinforced concrete beam design to Eurocode 2.

Reinforced concrete beam design to Eurocode 2.

Give Volex the section, concrete class, and design moment and shear, and it returns the required reinforcement with the full EC2 working: K and K', lever arm z, compression steel where needed, shear links by the variable strut method, and the span/depth deflection check.

The module is validated line-by-line against the standard UK reference — Mosley, Bungey & Hulse, 'Reinforced Concrete Design to Eurocode 2' — and against hand calculations of EC2 §6.2.2. The verification page shows every case.

Frequently asked

Is there a free EC2 RC beam design tool?
Yes — the free Volex tier includes 10 calculations a month covering the full EC2 beam check set with clause references. Pro (£29/month) adds unlimited calculations and PDF calc sheets.
Does it handle doubly-reinforced sections?
Yes. When K exceeds K′ the module designs compression reinforcement automatically and reports both layers with the EC2 §5.5 working shown.
What about shear link design?
Shear is checked to EC2 §6.2.2 (VRd,c with the v_min floor) and links designed by the variable strut inclination method of §6.2.3, with cot θ reported.
Is the calculation validated?
Every RC case is checked against Mosley, Bungey & Hulse worked examples and EC2 hand calculations — typically within 1%. The full table with errors is public on the verification page.
