Mechanical properties of corroded prestressed tendons were considered for the durability evaluation of prestressed concrete structures.It was verified that the stress has limited effect on corrosion rate of steel wire by corrosion tests for steel wires under high tensile stress and the effect may be neglected in the accelerated corrosion test.Prestressed tendons were placed in concrete and corroded by direct current to them.Through tensile tests,the mechanical behaviors of these corroded tendons were studie...
