Bending Moment & Shear Force Calculator

Calculate maximum bending moment and shear force for a simply supported beam with a point load at midspan.

Span length, LEnter span in metres.Centre point load, WEnter load in kN.

Condition

Simply supported beam with central point load

Maximum Bending Moment

30 kN-m

Mmax = W x L / 4

Maximum Shear Force

10 kN

Vmax = W / 2

This quick calculator assumes a single point load acting at the centre of a simply supported span. For UDL, eccentric loads, overhangs, moving loads or continuous beams, use the relevant structural analysis method.
