Beam Load Calculator
Result
Beam Load Calculator Find the maximum bending moment and support reactions for a simply supported beam carrying a uniformly distributed load (UDL). Enter the load per metre and the span, and the calculator returns the peak bending moment at midspan and th — free online calculator.
Formula
- Beam Load Calculator calculates its result from Wl. It uses the formula For simply supported beam with UDL: Mmax = wL²/8, Reaction = wL/2. Change any input to recalculate the result instantly.
- The main inputs are Uniform Load w, Span L. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Beam Load
- Uniform Load w: 8 kN/m
- Span L: 5 m
Using Wl = 2, the calculated result is 1.
