I would like to calculate the size of one, or two, I-Beams with a span of 32
feet for a new two story residential garage / house. The height of the beams is not restricted. New construction.
The beam, or beams, will carry the second floor 40 psf live and 20 psf
dead. We would like to have a clear span for the garage area so no posts.
The garage overall dimensions are 35.5' wide by 32' deep. Note that there is a 20' wide garage door roughly centered on the 35.5' side.
