2013年1月19日 · I have 20' and 25' w12x30 beams being installed in my home. Can anyone provide me with an estimate per foot what - Answered by a verified Structural Engineer

Customer: Hi...I am building an underground shelter and for the roof I have 9 - 24 foot w12x30 beams sitting on 3-24 foot - w12x20 beams all in upright position. One down each end and one in the middle.

W12x30 (50 ksi) steel beam. This beam is 6.5" wide, 12.375" deep and weighs 30 pounds per foot of beam.

So a w8x31 can support more than a w12x30 when used as a column? StructuralEng : Making a couple conservative assumptions about how the beams are attached to the columns, I would not go above 140 ton total.

The w8 beam will be install with bolts through the top flang to the trollies. There are two trollies on each end of the W8 (the trolleys go on the two sides of each of the W12X30 beam already installed. So four bolts on each end of the W8 and the trollies came with two 2x2 angle struts to be bolted on as well.

Now, let's consider the I-beam you mentioned, a W12x30. It has the following properties (approximate values): Moment of Inertia (I) = 160 in^4Section Modulus (S) = 26.7 in^3. We can calculate the maximum allowable bending stress using the formula: Allowable Stress (F) = Load per foot (w) * Span^2 / (8 * Section Modulus (S))

If I place 3,200 lb point loads at 36" o.c. spacing across a W12x30 (36 ksi) steel beam that spans 17', you are only using approx. 60% of the beams bending capacity, your beams most likely can be used again.

Hay bale density of approx. 11.25 pcfYou can use a W12x30 (50 ksi) steel beam for your 18’ clear span beam (with 10’ stack of hay loading). The beam is 6.5” wide and 12.375” deep. It weighs 30 pounds per foot of beam length. You will need to provide a 2”x8” wood nailer bolted to the top flange of the steel beams.
