The stress is usually imposed by tendons of individual hard-drawn wires, cables of hard-drawn wires, or bars of high strength alloy steel. Prestressing may be achieved either by pretensioning or by post-tensioning. To pretension concrete the steel is first tensioned in a frame or between anchorages external to the member.
