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.
