Beam Analysis

Description

Beam Analysis is a structural engineering tool for analysing simply supported, cantilevered and continuous beams. The app performs full Eurocode-compliant design checks for timber, steel and concrete members — including ULS bending and shear verification and SLS deflection control with creep effects.

Calculation Methods

• •Euler-Bernoulli beam theory (linear elastic analysis)
• •Macaulay's method (bracket functions) for moment, shear and deflection diagrams
• •Double integration of bending moment for deflection curves
• •ULS load combination per NS-EN 1990 eq. 6.10a / 6.10b (governing combination)
• •SLS deflection with creep — separate G/Q superposition
• •Equilibrium and compatibility solved at discrete points along the span

Standards

Norwegian National Annex (NA)

All partial safety factors, combination factors, and material parameters follow the Norwegian National Annex (Nasjonalt tillegg). Key NA references include Tabell NA.A1.2(A/B), Tabell NA.A1.1, Tabell NA.2.3 (timber), Tabell NA.6.1 (steel), and Tabell NA.2.1N (concrete).
