Now you know why studs come in 93s...when you figure out the 92 5/8s tell me so we both know

Edit: Chris beat me to it.


Basic math.

92.625+4.5-0.625"-96"=0.5

Precut stud plus bottom plate and double top plate minus thickness of ceiling gwb minus height of wall gwb leaves 1/2" at the base of the wall for construction tolerance, holding the wall finishes up above subfloor, etc.

If your walls are exactly 96" tall, you have to cut every piece of wall gwb.

FWIW, I started trying to find my old spreadsheet where I calc'd out the beam in my loft, then got distracted by pretty much anything, and never got back around to it.

Or just hand him the steel manual and let him do the math himself. No reason to make yourself liable.

Because this beam will be supporting one side of my 10" loft, the tributary load will only be 5' if I'm reading this correctly. 6' tributary load is ok for 20' span so it looks like I should be good with 1 post in the middle. I'll report back it it all falls down.

Assuming that pad was 20x30, what was the thickness? Trying to figure out ahead of time whether it is worth pursuing doing my driveway this year.

3.5" thick and had 2'x2x1' at all the post. I think it was around 8 yards of concrete at $175 - $200 yard at the time.

You'd have to check the fine print, but that's probably based on a 40psf live load. Make sure whatever it is actually matches your use case.

Yes, 40psf live load is what I was using. What would you suggest I base my numbers on? I don't forsee storing thousands and thousands of pounds up there. I have warehouses for that.

I don't have an opinion on the matter, just wanted to make sure you were aware. Some folks might see that chart and then plan on storing pallets of old blocks and heads or rows of shelving stacked with who knows what "up out of the way".

As a point of reference, typical office loading is 100psf (though vibration often controls) with 200psf or more used in places where high density files or other concentrated loads might be. 100psf might be high if you actually do the math, but it's to allow for unknowns down the road.

Thanks for the heads up. This will be more for Christmas decorations and junk like that. Possibly a hangout are for the kids with a pool table and foosball table in the future. 8' pool table would be the heaviest "thing" that would ever be up there other than live weight. It would be situated the long way so not too much of a point load in my mind. I've got a few spans of pallet racking I'm putting up along another wall for storing heavy stuff.

Stairs + Pool Table = Not Enough Beer In the World for me to help you get it up there! An 8' slate table is ~1000# plus.
