We room thinking of adding on to our house, 24' deep, 28 to 30' wide. The reduced level will be garage space, and it would certainly be nice to not have write-up in between the parking spaces sustaining a beam because that the floor above. The beam would certainly be extending the 28 come 30' width, for this reason I have the right to use 12' floor joist for the 24' depth. The ceiling hight in the garage area will certainly be 10 come 12' tall, therefore the hight the the I-beam wouldn't matter, together I can conveniently keep a 9' clear an are below the beam. The floor above will be bedrooms and bathroom area, I carry out not mental the tons per square foot for calculations, been 20 years since I had actually to think about it.Any feedback welcome, just in the brainstorming stage appropriate now, starting some sketches, to gain materials estimated, and cost figured.

I would architecture this v the beam in the 24' dimension. Most expectancy tables will permit much much more than 15' because that 2" x 12" joists of practically any types commonly provided for construction. A 24' beam deserve to probably be a GluLam using standard joist hangers because that the joists. 24' x 30' = 720 sq ft. Live load of 40 psf = 28800 pounds. 1/2 is supported by beam in facility = 14400 lb 14400/24 = 600 pounds/lineal foot. Look in ~ the table here: http://www.aitc-glulam.org/pdf/Capacity/DF_27.PDF and you would need either a 5-1/8" x 18" or a 6-3/4" x 16-1/2" Doug fir/Larch GluLam.This is no a particularly big beam and I would boost the dimension to 6-6/4" x 18" or even 19-1/2" to give a considerable increase in floor stiffness at a an extremely modest expense increase. P.S. As soon as you have this designed consider adding a hard point in one bay of the garage suitable for a chain hoist or even a come-along to usage as one engine hoist. I argued this to my neighbor about 20 years ago, and he placed one in. Once his climate 8 year old son entered his teen age years they must have actually rebuilt 3 or 4 engines together, constantly using the hard allude to remove and replace them.

Brainstorming? (insomnia) mine home's key floor is ~ above 18" deep 2x4 'W' trusses 24" OC and also interior walls room net 27' apart above where lock span. Over there is no beam, and also there's a raceway for the HVAC plenum under the truss centers. Household room listed below is 18' x 27' with no posts or beams.
