Driven Pile - Pipe to Cap detailing
Driven Pile - Pipe to Cap detailing
(OP)
I'm a structural engineer designing a steel pipe pile foundation (as required by the soils report). It's for a small manufactured metal building with a pile cap at each column.
Question: Are typical pile-to-cap details more complicated than embeding the pipe 6" into the cap? There are small tension loads to address. I only saw requirements for concrete pile-to-cap detailing in the IBC.
Thanks.

RE: Driven Pile - Pipe to Cap detailing
If you have any net uplift on the cap/pile interface, then some sort of attachment is warranted. This depends on the type of pile you are using.
Steel Pipes: weld a cap plate on top that extends out from the pipe diameter a small amount. or weld headed anchors around the exterior of the pipe.

We (contractor/architect/me) decided to go with grout filled pipe, as aeoliantexan suggested - the head connection is less of an issue and to address concerns about corrosion of the pipe. I will keep the cap in mind for future projects.
