About Beam Deflection

Calculates the maximum vertical deflection of a beam under load. Serviceability design limits deflection to span/300–span/500 to prevent cracking of finishes and user discomfort.

How It Works

Simply supported, mid-point load: δ_max = FL³/(48EI). Cantilever, tip load: δ_max = FL³/(3EI). Distributed load (UDL), simply supported: δ_max = 5wL⁴/(384EI).

Reference Values & Examples

  • 6 m simply supported beam, 10 kN midspan, W200×100 (I=113×10⁶ mm⁴, E=200 GPa): δ = 1.87 mm
  • Span/300 limit for 6 m = 20 mm — comfortably within limit
  • Cantilever deflection is 16× greater than simply supported for same span and load

Common Applications

  • Foundation and footing design
  • Structural beam and column sizing
  • Reinforced concrete quantity take-off
  • Retaining wall stability checks
  • Civil and structural engineering coursework

Did You Know?

The Roman Pantheon's unreinforced concrete dome (built ~125 AD) was the world's largest for 1,300 years. Modern structural analysis confirms it operates almost perfectly under compression — the only load concrete naturally handles well.

Common Mistake

Using the mid-span formula for a distributed load. The UDL formula (5wL⁴/384EI) differs from the point-load formula (FL³/48EI) — substituting one for the other gives a 5/8 = 62.5% error in deflection.
