Mounting A Shed To Concrete Slab

Problem - Trying to build a shed on an existing base.

I have an existing concrete base that has old completly rusted over threaded bolts sticking up from it... that were maybe one day intended to be used to secure a shed down to it.

The concrete slab is still solid and in good position for the shed i want to build. My question is, what is the best way to secure my shed to it? Conrete nails? Anchor posts at the corner edges of the slab? Or some other method?

shed will be approx 9' x 13' and stand about 6' tall... to protect lawn mowers and garden tools and water well.

Thanks

My first option would be to get a cheap tap and die set and try rescuing the threads on the existing foundation bolts.

Guess my next choice would be to use 3" Tapcon screws to anchor the walls with. If you go this route, lay down a couple of beads of Liquid Nails or some other adhesive or sealant under the bottom plates.

Nails, even out of a powder actuated gun like a Ram Set aren't a choice.

Wind load -- that's lift.

At the very least you would want to use either the existing bolts or a red head type anchor near each end of all 4 walls (2 per corner) and one near each side of the door (where the floor plate breaks for the door). Then using nails installed with a Ram Set in between those anchors will do OK.

Doesn't have to be a tornado. A 60 or 70 MPH wind would be more than enough to lift the shed off of the slab if you just use nails to anchor it. Wind over the top of the roof, no air movement underneath it -- LIFT.
