Shear Key in Pile Caps
Shear Key in Pile Caps
(OP)
Hi
I have a situation where I got huge shear, but not enough space to put lot of vertical piles . It is a industrial revamp job and the shear is due to combination of operational and wind load on the equipment. Can anyone guide me about designing a shear key in the pile cap.?
1. Are there special construction considerations for such a key.
2. What type of reinforcement is required in the key?
If there is any reference material available that will definitely help.
Thanks

Vertical steel reinforcing will not suffice?

Let me give you some background about the area. It is revamp job and there are existing large spread footings around the construction area supporting heavy equipment, built 20-30 years ago. There is no space to install batter piles. Even the vertical piles are a challenge with low head room rig, which the drilling contractor is willing to do.
Shear key is to add passive resistance along with the lateral capacity of the free head piles.
Thanks

I am not familar with helical piers. As long as head room and space permit, both could be good solution. However, the small diameter of the mini-piles and less restrictive in pile length are advantageous in many applications.
