The extreme stress at the top and bottom edges of a prestressed beam when tendons are placed along the longitudinal axis of the beam are
In post-tensioning, the elastic loss in a stressed tendon resulting from the shortening of the member when additional tendons are stressed is called as
As per IS 1343, at the time of initial tensioning, the maximum tensile stress immediately behind the anchorages shall be limited to p percent of the ultimate tensile strength of the wire, wherein p is
