title = "Load test of bonded post-tensioned concrete beams with corroded tendon",
abstract = "The paper describes ultimate load tests which were performed to show the effects of prestress and tendon corrosion on the flexural strength of post-tensioned concrete beams. Five test specimens were fabricated in laboratory with the variations of the prestress of tendons and the loss of tendon area. For two specimens, small area of tendon at the center of the beam was exposed by using diameter 25 mm drill and the exposed tendon was corroded intentionally using accelerated corrosion equipment. Test results show that the ultimate flexural strength of test specimens with corroded tendons is smaller than the predicted flexural strength which is calculated considering the loss of tendon area. From the comparison, it is considered that the estimation of flexural strength of prestressed concrete beams with corroded tendons is very difficult just based on the loss of tendon area obtained by one-side visual inspection. In addition, it is very hard to determine the effective tendon area which can be guaranteed to show fully ductile behaviors.",
