Had an engineer tell me one time that there is absolutely no structural value in concrete mesh, all it does is hold the concrete together after it breaks.
Few things I had done for my shop floor, at each door opening I went with a thickened edge. I dug a 12” wide by 12” deep trench.
On each side of the 6” x 12” posts the concrete crew nailed HTT-16 clips to tie the slab to the post. But one time I seen a set of blue prints for a pole barn there was a detail for drilling a hole through the posts and sticking a # 4 bar through the hole and bending it back at about 45 degrees into the slab area with about 3-feet long tails.
Do yourself a big favor, don't forget expansion joints! http://www.strongtie.com/products/connectors/LTT-HTT.asp
