Beam Deflection & Stress Calculator

Calculate maximum bending moment, shear force, deflection and bending stress for simply supported, cantilever and fixed-end beam configurations under point and distributed loads, with automatic section property lookup.

Calculate maximum bending moment, shear force, deflection and bending stress for nine standard beam and loading configurations. Enter factored loads for ULS stress checks or unfactored for SLS deflection checks. Does not check lateral torsional buckling, shear capacity or web bearing.
