Abstract:
An experimental investigation was carried out to study and evaluate the flexural performance of concrete beams reinforced with continuous fiber bars (main reinforcing bars and prestressing tendons). Two series of flexural tests were conducted, and the primary variables were fiber material, tensile reinforcement ratio, concrete compressive strength, and bond condition in prestressing tendon. Through this experimental study, the following facts were clarified. The flexural performance of concrete beams reinforced with continuous fiber bars can be evaluated by conventional methods used in concrete beams reinforced with steel bars. The ductility capacity of reinforced concrete beams can be controlled by the compressive failure of concrete, and in prestressed concrete beams, can be controlled by changing unbonded length of prestressing tendon.
