For beams subjected to uniformly distributed gravity loads where the shape of the moment diagram is known, the development lengths in Figure 1 can be used. These recommended details include the requirements for structural integrity reinforcement in …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).Yes, use 180° hook, need not to be in Europe. A 180 degree hook in a beam column joint performs quite poorly, so is not allowed in some standards. It's to do with anchoring of the diagonal joint force by the vertical leg of the 90 degree hook, and it forming a lap of sorts with the vertical column bars.Headed Bars are a simple and effective alternative to hooks and long development length.

With a hooked rebar, you need less overall bar length, and less straight development length of bar. I don’t have the ACI equations in front of me, but the straight length for a hooked bar is about half the straight development length. [deleted] • 6 yr. ago. I think my professor told us it is to prevent migration of the rebar through the ...

As per ACI 530-05, the design of anchor bolts is based on physical testing. The min embedment requirement is considered a practical minimum based on typical masonry construction. Although not directly applicable, it may be used to get an idea of the tension that can be developed by a hooked rebar.
