Concrete masonry unit wall pier reinforcement details showing horizontal ties and vertical rebar placement for 8-inch and 12-inch CMU piers. Vertical reinforcement is placed in the first cell with specific lap splice lengths and clearance requirements. Number 3 ties are spaced at 8 inches on center or used as vertical reinforcement in cells. Notes dictate application criteria where pier length is less than five times the wall thickness and pier height is greater than twice the pier length. Horizontal ties must extend lap splice length above and below openings with a maximum clearance of 1 inch and minimum clearance equal to the vertical bar diameter.
