Structural engineering - sizing a beam using loads/span

[steve321]

Hi!

I'm looking for information on how one would size a wide-flange beam knowing the live/dead loads and the span required

i can't seem to find any calculations for this sort of thing!

beam is not composite with floor

Try this:

Span/depth ratio will be roughly 10 for a heavy load, 20 for a light load, 15 for a medium load. Then you have to check stresses and deflection for a given choice of specific beam.
