Beam Calculator

Simple-span beam screening with uniform loading and a right overhang

1. Beam selection

Material / beam type

Beam section size

Number of plies

2. Span and supports

Clear span between supports (ft)

Right overhang beyond support (ft)

Bearing length at each support (in)

3. Uniform loads

Tributary width (ft)

Dead load (PSF)

Floor live load (PSF)

Roof live load (PSF)

Snow load (PSF)

Wind load (PSF)

Apply uniform loads across the full member length, including overhang

PSF × tributary width (ft) = PLF. Loads are treated as service loads.

4. Results

Total uniform load

Reaction at Support 1

Reaction at Support 2

Screening assumptions: one simply supported span with an optional right overhang; uniform loads only; rectangular section; plies act compositely. Generic material values are illustrative defaults, not manufacturer-published design values. This tool does not apply NDS adjustment factors or evaluate load combinations, lateral stability, connections, vibration, holes/notches, concentrated loads, continuous spans, or cantilevers at the left end. Deflection limits default to L/360 live and L/240 total, using the clear span. Verify actual product properties and have the design reviewed by a qualified design professional before construction or permit use.
