Custom Beam Calculator
Build a single-span beam with positioned loads and section properties.
Equations & calculation model
M = EI × curvature
Linear deflection and load effects use superposition with the selected support conditions.
Single span with constant elastic modulus and second moment of area. Linear elastic, small-deflection Euler–Bernoulli beam theory; ideal supports. Shear deflection, self-weight unless entered as a load, and design-code strength checks are excluded.
Standards & references
MIT Mechanics & Materials I: beam deflection and superposition; SCI P363: steel section properties. Uses linear, small-deflection Euler–Bernoulli theory with constant EI. Confirm section data, restraint, load combinations and the governing design standard; no code compliance is asserted.

ⓘ Assumptions
Single span with constant elastic modulus and second moment of area. Linear elastic, small-deflection Euler–Bernoulli beam theory; ideal supports. Shear deflection, self-weight unless entered as a load, and design-code strength checks are excluded.
Equations & calculation model
Linear deflection and load effects use superposition with the selected support conditions.
Idealised calculations for preliminary design. Check geometry, loading and boundary conditions against your application.
What it is used for
Compare supports, positioned point loads, distributed loads and moments for a single constant-EI span.
