My "new" 72-y/o house is... interesting. The garage is much younger but still I just raise my eyebrows at some things.
One of them is the loft/attic area in the garage. I wanted to move all my computer hardware up there, of which there is a LOT. But just walking down the middle of the floor got me uncomfortable. It deflects too much.
The previous owner used 2x6 as joists, nailed (3x) to the side of the 10' stud ~8' up. The span is 15.5' ... since the ends are not on a sill and nailed IDK if the full 16' would be considered as the span. Regardless, SPF 2x6 with 16" spacing are rated for about a 9.5' span.
I'm trying to avoid removing and reinstalling the floor if possible. My intention was to double up the joists in 5 evenly spaced spots (every 3 stud spaces)... I'll do everyone if needed though. I can't find a span calculator with arbitrary spacing or joist dimensions.
Would this work? What is the resulting span from doing this?
My intention is 2x6 joist - 2x4 stud - 2x6 joist. I'm using it for business purposes but want it to remain usable as a garage whenever I leave this place.... so no beams and posts down the center.... if the thought had occurred to you. :)
