steel beam sizing

Posted by knick (My Page) on

I am looking for some guidance, I am building a room inside a pole barn. It will be 16' wide X 20' Deep. The Ceiling above will be for storage of normal household type items. One side of the room will have a stud wall the other needs to be open. I want to put a steel beam on that side to carry the ceiling load. I have found a sizing chart and have figured the beam size. I would like anyone to jump in and tell me what you think. The Formula I used I found on the web. the design loads are as follows:
Floor dead load - 10 psf
Floor live load - 40 psf
Roof dead load - 10 psf
Roof live load - 20 psf
vertical load one story = 62
Clear span x joist/2 x vertical factor = / 1000 = KIPS

I came up with a 9.92 kips
So it looks like a w8x13 (11 Kips) would be the one to go with unless
I could go with a w8x10 (9 Kips) because I have no roof load.

Any thoughts?

Thank you for your time

A PE stamp is normally required for steel beams.
The beam cannot be sized without a detailed drawing of the application.
