In the case of a concrete cantilever wall, I have seen details of the hooked bars from the vertical wall reinforcement turned inward and also outward (see attached images). Documents on CRSI's website claim that turning the hooked bars outward do not develop the total moment in the wall, but highway standards and even ACI details show the hooked bars turned outward.Could anyone offer their opinion or experience on which is the correct way to detail this connection?Thanks
In the example you show, the tension steel in the wall stem is on the left. By turning the hook outward-to the left-you would be putting the hook in a portion of the footing that is in compression. This is preferable. The wall reinforcing on the right side of the stem is for crack control and the orientation of the hooks really doesn't matter.
