Steel Pile to Concrete Grade Beam
Steel Pile to Concrete Grade Beam
(OP)
How would one typically connect a steel pile to a grade beam? We are specifying steel piles for our one storey structure and was wondering if there is anything that I have to keep in mind when I am designing my grade beams or spacing the piles. Grade beam width varies from as narrow as 8" and is currently spaced at 15' o/c. I'd hate to make the pile contractor's life difficult by giving him a design that is very difficult for him to work with.
Thank you.
Thank you.

Are you trying to develop moment capacity of the H-pile?
We use steel pipe piles into concrete cap beams all the time in our marine projects. We've been using headed dowels a lot lately since you avoid the need for all that rebar hook developmant length.
How do you intend to structually fasten the pile to the grade beam?

Bobber, I am thinking that the H-pile will be embedded to a certain depth. I am just worried, as you have expressed, that the grade beam width is too narrow to do that.

1st - I don't leave the pile design up to the contractor. I am not familiar with this practice. How is this done?
2nd - The final pile location will not be centered on your grade beam and some moment will need to be developed between the grade beam and pile for torsion, lateral loads, etc...
3rd - I've never seen an 8" wide bucket for earth excavation.
4th - Smallest H-pile is 8" - How are you developing the rebar to either side of this as called for in CRSI?

BA - no uphand welding would be required for the plate, if it is an 8" H-pile, use a 7 1/2" plate and just put 1/4" fillet weld across both flanges. Should be more than adequate for whatever load is being carried by the pile.
RE: Steel Pile to Concrete Grade Beam
That is true, but if the pile is a little off line, a 7.5" plate doesn't give you much room for error with an eight inch grade beam.
