Reinforced Opening in Concrete Wall
Reinforced Opening in Concrete Wall
(OP)
I am designing the reinforcement for a six (6) foot diameter opening in a 17" thick submerged concrete wall. I have based prior designs on the simple rule of replacing each cut rebar with two (2) 45-degree diagonal bars about the opening. Using this premise in this case , I've got twelve (12) diagonals in each quadrant around the opening, which appears excessive! The opening crosses the midspan of the wall where higher bending moments have been observed. Any suggestions?

If you have a lot of holes, then you might want to take a closer look and maybe save some reinforcing.
