A one-way post-tensioned concrete slab is supported by cast-in-place concrete beams. The section details the profiles of draped post-tensioning tendons spanning across exterior and interior bays, with tendon heights measured to the center of gravity of the steel. Top and bottom reinforcing bars are placed per plan with specified clearances, including additional continuous number four bars with 180-degree hooks at the slab edge. Bottom reinforcement splices are staggered to prevent splicing more than half of the bars at one location. Temperature tendons are spaced evenly across each span to provide the required compression.
