About this detail

Standard concrete wall reinforcement details establish minimum sizing and spacing requirements based on wall thickness ranging from six inches and under up to twenty-four inches. Horizontal and vertical bars are arranged at centerlines or on each face with specified lap splice lengths. Joint elevations show keyed construction joints or intentionally roughened surfaces with alternate spacing. Wall corners, intersections, and ends detail standard ninety-degree hooks, corner bars, and tie configurations for single and double layer reinforcing.

NOTES: 1. UNLESS NOTED OR SHOWN OTHERWISE, ALL WALLS ARE TO BE REINFORCED WITH MINIMUM REINFORCEMENT AS SHOWN IN THE FOLLOWING TABLE: 2. LAP VERTICAL WALL REINFORCING Lsb AND HORIZONTAL WALL REINFORCING Lsbt AT SPLICES. 3. ALL VERTICAL REINFORCING IN CONCRETE WALLS SHALL BE CONTINUOUS FROM STRUCTURAL FLOOR TO STRUCTURAL FLOOR, OR FROM FOOTING TO FIRST STRUCTURAL FLOOR ABOVE UNLESS NOTED OTHERWISE. 4.
