Use of non-metallic (FRP) reinforcements provides a promising alternative in order to avoid corrosion in reinforced concrete. By applying non-metallic (FRP) reinforcements there is no ferrous material to corrode in reinforced concrete. This paper reviews experiences with Carbon Fiber Reinforced Polymers (CFRP) for precast prestressed concrete girders. An experimental program was completed at the Budapest University of Technology and Economics, Faculty of Civil Engineering to study service behavior of precast concrete beams prestressed with CFRP tendons in terms of both load vs. deflection responses and cracking behavior. In this paper deflection control is presented with an introduction of a new simplified method and discussion of pivot hysteresis behavior under cyclic loading.
