try this website it might help - http://www.engineeringtoolbox.com/beams-support-forces-d_1311.html first off the calculations are based on beam size (example w14x26 [14=14" x26=lbs. ) which is around 5 3/16" wide x 13 7/8" high the flange thickness is around 3/8" thick and the web would be 1/4" wide you also must check the span and application (concrete Pier's, or schedule 40 columns (1/4" thick steel column) there are other factors which are involved in other words consult your engineer
The calculation of quantity of steel in a beam is steel quantity is equal to 1 percent of concrete quantity. Another way to measure it is steel quantity is found by multiplying number of bars by length of one bar by unit weight of steel where the unit weight of steel is d up to 2 divided by 162, d minus is the diameter of the bar.
Load the beam until it breaks, weigh the items that broke it.
If you recon a medium sized beam will do the job, but you are not so sure, follow this simple fomula.
medium sized beam x doubt = Bigger beam
It depends on if the roof is flat or slanted. Flat roofs have a 25 lb. per square foot load bearing ability while slants can be up to 50 lbs.
The size of a steel beam is calculated by measuring the beam horizontally and vertically. The thickness of the beam caps is also measured vertically.
Steel Cannot be calculated based on cft. Load bearing capacity is required to calculate steel.
Steel I beams
The "W" in steel I-beam designations refers to wide-flanged beams. Most wide-flanged beams are symmetric about both the vertical and horizontal axes.
Universal columns (or beams) are H-shaped steel joists with parallel flanges which are thickened to carry an axial load (or bending load). The "top and bottom" flanges of the Ɪ girder are slightly thicker than the middle.
Almost any solid horizontal structural member is considered a beam. They are usually steel or concrete and are used to transfer a vertical load imposed on the span (middle) of the beam to the ends or vertical supports of the beam. Steel beams are probably what most people think of when picturing a beam. W-sections (formerly known as I-beams, but are modified by the strength/type of steel and the cross section shapes) are the most common steel beams used. Concrete beams are often used in foundations and can be best seen above ground in parking garages everywhere. There is always a good amount of reinforcing steel in a concrete beam to carry the tension that occurs in the bottom of a beam so the concrete won't fracture.

For finding reactions for simply supported beam with uniformly distributed load, first we have to convert the u.d.l into a single point load. And then we have to consider it to be a simply supported beam with a point load and solve it. I think you know how to calculate the reactions for beam with point load.
Among our handy steel beam tables you can find standard beams' dimensions and beams' weights, steel hollow sections tables and other steel profiles data.

You can purchase steel beams from anywhere from Home Depot to Global Industrial. Global Industrial is the number 1 location for this type of material.
