Seismic Connection to Pile Cap

Seismic Connection to Pile Cap

Seismic Connection to Pile Cap

(OP)
I am planning to utilize precast concrete piles for a foundation in Seismic Design Category C and IBC 1807.2.23.1.1 requires concrete piles to be connected to the pile cap by embedding the pile reinforcement or field placed dowels anchored in the pile cap for a distance equal to the development length.

Field placing dowels make sense if it was a concrete filled pipe pile but a little labor intensive to drill and epoxy hundreds of precast concrete piles.

Can anyone offer their experiences in making this connection with a precast prestressed pile without using longer piles and breaking up pile to expose tendons?

RE: Seismic Connection to Pile Cap

Detail the top of pile with embedded rebar connectors such as Lenton?

JAE thanks for the suggestion, but I don't think that will work.  After piles are driven to capacity, pile tops have to be cut off to proper elevation.

RE: Seismic Connection to Pile Cap

Any pile in SPC C, should be embedded at least 18" and thus should have ample room for connection hardware/rebar.  

I didn't get this from a code, just experience.
