The tendons are then anchored at each stressing end. Tendons may be stressed from one end with the other end anchored or may be stressed from both ends. When the concrete has reached its required strength, the tendons are tensioned. The steel tendons are usually in place, unstressed in the ducts during the concrete pour. In this method, the concrete is cast around hollow ducts which are fixed to any. Pretensioned concrete members are often precast in pretensioning beds long enough to accommodate many identical units simultaneously. The stress is imparted via bond between the steel and the concrete. As the highly stressed steel attempts to contract, the concrete is compressed. When the concrete has reached its required strength, the wires are cut or otherwise released from the abutments. With the formwork in place, the concrete is cast around the highly stressed steel tendons and cured. ![]() In this method, the prestressing tendons are initially tensioned between fixed abutments and anchored. ![]()
