Frictional Loss of Prestress by Locally Deflected Tendon at Continuous Joint of Prestressed Concrete Girder bridges
PSC continuous girders have been used to improve the stability of simply supported girders. The loss of prestress is one of important factors for rational design and construction of the PSC girders. Measurements of prestress loss were conducted with the several test variables that reflect the conditions of continuous joint. Results show that the prestress loss is closely related to a eccentricity.
