temperature reinforcement left out
temperature reinforcement left out
(OP)
I have a one way pan joist floor. Typical bay sizes 24'x24'. 30" pans, 4 3/4" slab, 16" deep stems. The temperature steel was left out in the middle third of the bay. Shrinkage cracks have occured where the temperature steel stopped. My question is: Does the temperature steel serve any other purpose other than crack control? Does it assist in transferring load to the concrete joists from the slabs? If the temperature steel serves purpose other than crack control, what can be done to get steel into the areas where there is no temperature steel?

In my opinion, an exterior slab would require the epoxy injection of the cracks or an epoxy topping to prevent deterioration of the slab and remaining rebar. If interior, then it is not so critical and perhaps a floor coating would be adequate, since it would be more of an aesthetic problem.
