The W12x14 is acceptable for that span and load, but it does require the joists be detailed to brace the beam against lateral torsional buckling Read less 0 Likes

Customer: I am supporting grating that is 84" x 36"- 2.5" x 1/4" bearing bars with three W12x14 lb I beams and the concrete edges of the trench. The beams rest completely on the concrete tunnel floor.

It says that 5, W12x14 beams will carry 20,000 pounds with 20 feet of free span. If the span is reduced to 10 feet by adding columns, can it handle 40,000 pounds? Answered by StructuralEng in 1 hour 8 years ago

2012年11月18日 · This W12x14 steel beam will support a 5' wide tributary load of a 20 psf Live Load and a 10 psf Dead Load walkereng : You will need to provide solid mechanical connections between each of your 2x8 roof rafters and the steel beam top flange.

2. Three W12x14 (36 ksi) steel beams between the exterior beams. 3. The connections of all the beams and intermediate diaphragms are in good shape and adequate. 4. The timber decking is in good shape and adequate. 5. Truck loading is an H20 truck, two axles, 32,000 lbs and 8,000 lbs that are spaced 14' apart

A W12x14 or W8x18 would be able to hold a 20'-0" span. End reactions would be 5,000lbs. ~JAYCE GREFRATH, P.E.

Since non of the roof trusses land on the steel beam, a w12x14 should be fine. As I said above, you will need to have a local engineer detail your connections, size your support columns, and determine foundation requirements.

The lightest 12" beam would be a W12x14. This beam is 4" wide and 11.875" deep and weighs 14 pounds per ...

I would recommend using a W12x16 for the center beam and W12x14 for the end beams. You could also use a W8 or W10 beams, which would be less deep, but would cost more since they would be heavier. If you used 5 beams instead of 3, you could reduce the depth of the beams, but the cost would increase since you have more steel.
