Results on pull-out tests agreed with Bach’s tests on beams [4] , which exhibited an increased flexural strength due to end anchorage and demonstrated that the shape of the anchorage and …

Hooked Rebar Anchorage vs. nVent LENTON Terminator For many years, the traditional method of connecting roof/column and beam/column connections has been with hooked rebar anchorage. But as many structural engineers, architects and specifiers have discovered, this method of anchorage has very few advantages. I would run 4 - #4 rebar vertically in the column and install 4” hook (90 degree bend) in each rebar and extend it into the footing 8”. 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.)Reinforcement can be developed by embedment length, hook, or mechanical anchoring device. The development of the reinforcing bars relies on mechanical interlock of the bar deformations, hook, and/or anchor along with sufficient masonry cover to prevent splitting of the masonry.
