Retrofitting of Reinforced concrete Pile Cap
Retrofitting of Reinforced concrete Pile Cap
(OP)
Hi Everybody,
I have a existing four pile cap, It was decided to add two more new pile and join to the existing foundation by
Hilti epoxy Rebar. It is joined by the shear rebar as shown in the figure.
(a) Rebar transfers the shear force from the two pile cap to the existing pile cap at the joint.
(b) If she shear is taken by the shear rebar, what is the length of rebar to be embedded in concrete?
(C)If all the shear is transferred by the shear rebar, the concrete at the joint should also have enough shear capacity ?

1) Shear friction at the joint.
2) Regular diagonal tension at the joint.
Your design should also consider any other forces present at the joint. If there is significant moment, you'll want most of your rebar on the tension side. Hilti has some great resources for the design of these kind of joints,
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.
