need help on footing sizes for a 50 x 100 steel building
(OP)
in the foundation phase of a new 50 x 100 steel building. Didn't realize the footings plan didn't come with the building. I don't want to go overboard with concrete but also don't want trouble in the future. Any help would be appreciated. The building is a clear span, 4 bay on 25' spacing with 3 sets of main beams. I'm in eastern NC so frost heave is not an issue. I'm planning 24" deep x 36" x 36" for the main column footers with a perimeter footing of 18" x 18" maybe slightly wider on the end walls. My question is... is this enough ?? My understand is wind uplift is the main priority with having enough concrete. We are in a hurricane area. I've seen one other post on here and they were saying 4 ft x 4 ft x 4 ft footers for the main columns.... this seems like overkill to me. Thanks in advance !

And when you squint and look a the fine print, it turns out that the PEMB's supplier's anchorage is just a suggestion, so you're responsible for that, too.
Hire a structural engineer. Look at it this way, you got a cheap building, pay a little for an engineer.

Hire a structural engineer to work up your foundaiton plan. Fair warning though, the structural engineer will want a geotechnical study.
f-d

Hire a structural engineer, licensed in NC, to design the footings for you. These would depend upon your local soils conditions and loading.
You can't use someone else's building to design your footings as things could be different at your site such as:
1. Wind loads can vary with location and site contours
2. Seismic loads can vary
3. Column reactions thus will be different.
4. Snow loads can be different
5. Soil load bearing capacity can be different.
When I say "different" above I mean anywhere from slightly to vastly different.
Also - depending on where you are building this you may or may not legally be required to use a licensed engineer.
Even if you are not technically and legally required to use an engineer you would be foolish to not do so.

Oh, and make sure whomever you use knows what a "hairpin" is and what it's function is. If he doesn't, don't use him (or her)...
