...what the maximum clear span of a W12x14 steel beam is, for standard residential loadings IRC2000 [I think it's 45 PSF & 10 PSF dead load]. The "tributary area," on either side, as best I can figure, is 12'. [It's a 36' barn, and there are two girders across--I want to make the one above the open area steel, to (a) use one of those leftover steel beams from the house and (b) avoid a column in the open area, or move it as far over as possible, to give maximum equipment-driving-in, etc., space...
I found various programs that seemed like they might give me the answer if I set up the problem correctly, but couldn't puzzle my way through it.
I don't have time to run through the math right now, but I think you could use the equations from this Google Answer
, and solve for l, plugging in the moment of inertia (I) value of 88.6, which is what this page
gives for a W12x14 beam.
Sorry - just realized that the two variables I used look identical in Arial. The first is a lowercase L, and the second an uppercase I (the letter after H, that is).

Your steel supplier will have all this information. It's pretty standardized, and at least for aluminum, charts exist for that kind of thing -length of span v. loading, etc.
