I have to design a turndown slab. Slab on grade with thickened section at perimeter winding down to the thickness of the slab on a 45 degree angle. This is for a prefabricated metal building having a span of 40'. The rigid frames are spaced roughly 25' c/c. My concern is for the point load...
Orford : Use the loads for St-Denis-de-Brompton located less than 15 km away, and roughly the same elevation.
Ss = 46.0 psf (ground snow load)
Sr = 12.53 psf (Rain Load)
Wind Pressure ( 1/50 years ) = 6.70 psf
Refer to the Canadian National Building Code 2005 part 4 if it is a commercial or...

I was wondering isf anyone knew how to determine the hairpin required length to be embedded in the slab.
I have 15 kips. If I use 0.9 x .750(#6 bar) x 60 ksi = 37.8 kips. If I wish to determine how long I need the hairpin to penetrate into the slab.
