0.0018*b*h rho for Very Thick Slabs
0.0018*b*h rho for Very Thick Slabs
(OP)
As ACI states, the minimum temperature & shrinkage steel is 0.0018*b*h. The question is at what depth does the bottom steel not provide relief for cracking at the top surface? Clearly, the bottom steel of a 10' deep, doubly reinforced foundation would not help at all, and your top steel alone should prevent the cracking. Great, but what d should you use in that case?

If this amount turns out to be greater than rho minimum, just use rho minimum.
