20 lbs per square foot? that doesn't sound right. if I stood on one foot I would overload that area by 10 fold?From my findings many state that average sheds can hold 20lbs per square foot. Supposedly giving the average shed about a 2400lbs weight capacity.
The way they are made it would be dead simple to "beef up" the area you want to put the safe in. Just make sure before you beef up you have the shed where you want it. Don't want to beef up the area then later decide you want to move the shed.Thanks for that idea. I called up Tuff Shed and they said my model (which actually is 24in on center) is rated at 75lbs per square ft. Definitely not enough for a safe!
I agree, I didnt do the math.. its simply what was quoted on a few different Tuffshed forums Q's. By chance they could have meant 200lbs.20 lbs per square foot? that doesn't sound right. if I stood on one foot I would overload that area by 10 fold?
That said, in the past I placed a of 3/4 inch plywood under my safe to spread the load, also if not on concrete I also locate my safe in a corner that is load bearing.For residential floors, the live load is usually considered to be 30 to 40 pounds per square foot (psf), although this varies depending on the location within the home. First-floor live loads have higher requirements than second-floor live loads (40 pounds per square foot vs. 30 psf)
Concrete on the perimeter, gravel between the concrete.What's underneath the shed, dirt, gravel or concrete?
Good idea.I think I'll just site it in the garage on concrete. It'll necessitate moving things around, but I can accommodate it.
That's not how you look at a floor rating. The requirement for residential sleeping areas is 30 psf. That doesn't mean that if you took a 50 pound, 1 square foot weight and placed it on the floor it would fail. The capacity of the flooring system is taken as a whole and must meet the psf requirement when divided by total area. However, a safe can result in excess deflection. Always good to check span tables. Source: am engineer20 lbs per square foot? that doesn't sound right. if I stood on one foot I would overload that area by 10 fold?
Good call - I'd say that's the better option.I think I'll just site it in the garage on concrete. It'll necessitate moving things around, but I can accommodate it.
