Floor Slab Thickness Design Using PCA Charts for Rack Storage Post Loading 2

[jheidt2543]

I have a floor slab to design to support storage rack W6 posts with a 14 kip load. The PCA Charts do not have a wide enough range for the X and Y distances between posts to cover my situation (X = short distance = 138" and Y = long distance = 240"). I'm wondering what others do when they run into this situation; look at each post as an individual load, analyse it as a beam on an elastic foundation, other?

jheidt2543...shear will probably control unless your post spacing is quite close. With your spacing, the slab will not likely act like a beam, but will have an isolated punching load.
