Structural Design › Beam calculator
Beam calculator – cantilever, simply supported, fixed and continuous beams
Bending moment, shear force and deflection diagrams for single-span and continuous beams with point loads, UDL and linearly varying loads.
Calculation method
Beam elements (stiffness method) for every support type, with the closed-form Macaulay-bracket equations shown for single spans (point load, UDL, linear load); continuous beams with load patterns and moving loads (members).
