This calculator is based on Euler-Bernoulli beam theory. The Euler-Bernoulli equation describes a relationship between beam deflection and applied external forces. The simplest form of this equation is as follows:

Of course, it is not always possible (or practical) to derive a closed-form solution for some beam configurations. If you have a steel, wood or concrete beam with complex boundary conditions and loads you're better off solving the problem numerically with one of our finite element analysis tools. If you're not worried about design codes and comparing beam demand and beam capacity, try out our easy to use Shear & Moment Calculator. If you need full design checks via AISC 360, NDS, ASD and LRFD for steel or wood beam design and you want to design your next beam in minutes, you might like our Beam Designer tool.

Welcome to the Beam Calculator. A free, online beam calculator to generate shear force diagrams, bending moment diagrams, deflection curves and slope curves for simply supported and cantilvered beams. Select a beam and enter dimensions to get started. Then scroll down to see shear force diagrams, moment diagrams, deflection curves, slope and tabulated results.

Design multi-span beams with complex loads with WebStructural's intuitive interface. An interactive drawing area allows you to design complex, multi-span beams in minutes.

We use these equations along with the boundary conditions and loads for our beams to derive closed-form solutions to the beam configurations shown on this page (simply supported and cantilver beams). The beam calculator uses these equations to generate bending moment, shear force, slope and defelction diagrams.

The beam calculator is a great tool to quickly validate forces in beams. Use it to help you design steel, wood and concrete beams under various loading conditions. Also, remember, you can add results from beams together using the method of superposition.

Choose from a wide variety of steel and wood shapes. AISC steel, NDS wood shapes with shape properties to help you meet the demands on your beams.
