Would this reinforcement splice work ?

Would this reinforcement splice work ?

Would this reinforcement splice work ?

(OP)
Hello guys,

I'm in a situation where, for a splice length, we can't use the full development length of the rebar.

Does the following attached detail work in such situation?

IMHO, conceptually it works great, but I don't see it covered in ACI 318 so maybe I'm missing something.

What are your thoughts?

RE: Would this reinforcement splice work ?

I'm not sure it's street legal but I've done it myself with Ldh on 180 hooks with a transverse bar in the bend.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

RE: Would this reinforcement splice work ?

Another road to go down that would be street legal is a strut and tie analysis. If you can prove that it works by strut an tie, then it probably works. The attached article shows an example for a different situation.

As KootK notes, can you use a 180 hook? or can you weld if distance is short?

I'm not very keen of welded splices, it's just something rarely specified.

A 180 hook would also work. A strut and tie model seems the way to justify it.

I still wonder why this is not covered somewhere prescriptively, it doesn't seem like a extremely rare situation.

RE: Would this reinforcement splice work ?

It's come up in exactly one case for me: delay strips with whiny contractors.
