I am in the design stage for a little garage. Initial plan was to go 20x24....with trusses spanning the 20'.
Then a neighbor offered me some free trusses that were from a deconstructed garage. Problem is I dont know if they were 2'OC or 4'OC and they are 24' span
They are a common truss, and all 2x4 construction. But he only has 6 of them.
I think the building would not look right if the eve wall were only 20' with the trusses (gable wall) spanning 24'. I think it would look dis-proportional. So am considering just a square 24x24 which would require 1 additional truss.
My Google-fu dont seem to be working well this morning....cause I cannot find any info on 24' trusses....either 2' or 4' on center.
Most polebarn trusses around here only need to be designed for 25-30 PSF ground snow load. And I know when I built my shop with 40' trusses....4' OC, they were all 2x4 with a 2x6 top. Same with my buddies 32' trusses. So my question is...with a 4'OC post-frame truss.....at what span is that 2x6 top required?
I know residential trusses, from 10' span up to 30'+ spans are usually all 2x4 construction. But obviously a 10' or 12' truss with all 2x4 is massive overkill.....but its simply because 2x4 is the smallest common dimensional lumber. As well as most residential trusses are built for greater loading anyway cause they are assuming sheathing/shingles and drywall ceilings with more insulation.
My gut tells me an all 2x4 constructed truss is gonna be fine at 4'OC.....but was hoping someone has either built a 24' span building and can share their truss's engineering drawing, or can find one online somewhere that seems to be eluding me at the moment.
