Engineering Tools
Practical preliminary design tools for structural engineers, architects and construction professionals. These tools provide rapid indicative checks during early-stage design and should not replace project-specific engineering analysis or professional judgement.
Preliminary Beam Sizing
Undertake an initial beam sizing check to support early-stage structural design and option development.

Tool
Beam Deflection Check
Simply supported beam under a uniformly distributed load: δ = 5 w L⁴ / (384 E I). Enter unfactored (SLS) loading. Common limits: L/360 (general), L/500 (below brittle finishes), L/250 (total including permanent).

Tool
Preliminary Beam Sizing
Simply supported beam under a uniformly distributed load. Enter span and unfactored loads; the required plastic modulus is calculated to BS EN 1993-1-1 and a suitable UB section is suggested from a shortlist. ULS combination 1.35 Gk + 1.5 Qk; deflection to L/360 (SLS unfactored).
