Span calc for dimensional lumber

I finally got this thing working I think. This is for uniformly loaded simple beams.
I think the awc. org span calc is the "go to" for joists and rafters. It falls short when you get to built up beams, headers, and girders. I've spot checked with their spans and adjusted design values and seem to be getting good numbers. Give it a whirl.
