Openings and Embedments in Precast Sheet Piles
Openings and Embedments in Precast Sheet Piles
(OP)
What's the/a standard for providing reinforcing around/near/for/etc. an opening in a precast, prestressed concrete sheet pile?
Here's what I've got: bulkhead made from precast, prestressed interlocking concrete sheet piles (I'll call them "piles" from here). They're anchored to an existing bulkhead (steel sheet piles) by means of anchorage hardware embedded at the appropriate location in a particular pile. This anchorage hardware comprises two steel angles, L2.5x2.5 with 2.5 inch studs @ 3 inches welded to the angles. The tie-back's nut/plate/etc. assembly bears directly on these angles. Thus, there is a "hole" in the pile that's 1 ft x 4 in.
Question: should there be any additional reinforcing about this hole? We've got the steel angles, but there's no cross-reinforcing at the corners. I don't necessarily think it's needed.

RE: Openings and Embedments in Precast Sheet Piles
Usually it is a good idea to provide #4's rebars at 45 degree angle at the four corners of the opening to arrest any possible crack originating from the corners.
At each hole, there will be the concentrated reaction of the anchor. That reaction should be distributed to the
"continuous" strips of the sheetpile by the angles or by added horizontal rebars.
