# How do you calculate steel beam size?

## How do you calculate steel beam size?

Measure the distance in inches that you need the steel beam to fill. Write this figure down on a sheet of paper as your clear span for the beam. Measure the length in inches of the floor joist that the I-beam must support. Divide that number by two.

## How are weight beams calculated?

Curved beams 1. Standard weight: The standard weight for curved beams is computed as follows: G = L * mweight, where L is the length between the extreme points of the beam body (all features except holes considered) along the beam physical arc (offset taken into account) mweight is calculated as above. 2.

**How to calculate the size of a steel beam?**

If you have a steel, wood or concrete beam with complex boundary conditions and loads this is a great tool for solving the problem numerically. If you’d like to validate this calculator use our closed-form beam calculator to compare results: Beam Calculator.

### How to do a beam calculator on the web?

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. 1. Select a beam 2. Change dimensions to recalculate 3. Review results

### Which is the best tool for steel beam design?

If you’d like to validate this calculator use our closed-form beam calculator to compare results: Beam 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.

**How to calculate the deflection of a beam?**

The sign convention used in the shear force and bending moment diagrams is (positive values shown): Using the cursor to hover over any point on the bending moment, shear force or deflection diagrams gives the specific values at that location along the beam.
