About this detail

A single span post-tensioned concrete beam features continuous top and bottom reinforcing bars anchored with standard 90-degree hooks at each end. Transverse stirrups are spaced throughout the span according to the structural plans and schedule. The post-tensioning tendon follows a parabolic profile spanning between stressing ends, with the center of gravity of the strand located at specified dimensions from the top and bottom faces. Additional top reinforcing bars extend over the supports for a distance of one-sixth of the clear span, and additional bottom reinforcing bars extend through the midspan region for one-third of the clear span.
