Reinforcing bars terminate at the face of support with standard 90-degree and 180-degree hooks. The development length ldh is measured from the face of support to the outer edge of the hook. Bar tension is calculated as T equals Asfy. Standard hook sizes and bend diameters D conform to standard hook and tie detail requirements.
