I am designing a footing where Temperature and Shrinkage steel controls.

If say #5 @ 12" o.c. is required do I need to provide this steel in both directions or just one?

Thanks!!

just as a note for slabs positions close to a free edge (e.g smaller slabs in particular) no temp. shrinkage rebar is required since there will not be enough shrinkage strain developed i.e. over the tensile strain of concrete.
