Make sure the vertical bars are about 1” clear from the edges, so concrete can encapsulate the rebar. For that height of column, I’d use #3 ties at 12” oc. (#3 rebar you can bend by hand.)hooked bars (hooked bars with center-to-center spacing less than 6 db). Closely-spaced hooked bars exhibit less anchorage strength than widely-spaced hooked bars. The reduction in anchorage strength of closely-spaced hooked bars is a function of both the spacing between hooked bars and the amount of confining reinforcement.The hooked rebar from Mexico was produced and/or exported by Deacero.

Were that the case, we'd be utterly ... Rebar J Hooks are also beneficial for preventing lift in areas of extreme freeze/thaw cycles. 3” and 4” cell depth grids use the 18” height (JHR18) 6” cell ...The steel strength in tension was the governing failure mode in my case. Below is a snip of the check from Simpson Anchor Designer. It's done using a Gr. 55 hex head bolt that way the pullout didn't control, but I think all the other checks should be pretty consistent with the #4 hooked dowel (Gr. 60 rebar).Terminator Coupler is a simple and effective alternative to hooked rebars.
