About this detail

This structural detail outlines the reinforcement requirements for rectangular and circular openings in concrete walls, slabs on grade, and flat slabs. Extra reinforcing bars equal in size and number to the interrupted bars are placed half on each side of the opening, with a minimum of two number five bars each face. Additional corner and trim bars, such as number six bars for walls or number five bars for slabs on grade, are required when opening dimensions exceed one foot six inches. Cored openings are prohibited in concrete walls or slabs, and embedded conduits or pipes must be routed through sleeves or blockouts rather than embedded directly within the concrete.
