Beam Deflection Superposition Calculator

Calculate beam deflection by superposing multiple load cases: point load, distributed load, and moment on simply supported beams.

Span of the simply supported beam.
mm
Steel: 207 GPa, Aluminum: 69 GPa.
GPa
Second moment of area of beam cross-section.
mm⁴
Point load at midspan (0 if none).
N
Uniform load per unit length (0 if none).
N/mm
