Reinforcement around openings in slabs and walls
Reinforcement around openings in slabs and walls
(OP)
Hi Every one,
Dose anyone know the principals of sizing extra re-bars (diagonals, and vertical, horizontals) around wall openings in reinforced concrete walls and slabs?
Is there calculation or just code requirement?
The wall that I am working on has a 14" pipe going through at the base of wall - it is a retaining wall (I don't know the rules are different for retaining walls compare to ordinary building walls?
Please direct me. If you know of any good reference I will appreciate letting me know.
Sincerely,
BFstr

The diagonal reinforcing is added to provide a smooth load path around the opening. I've never seen any literature that presents the theory. It's just a standard practice in the industry.

For very unusual situations with multiple holes or high diaphragm stresses, a more in-depth analysis (FEM) may be warranted.
