  • Abstract
    This paper aims at the problem of prestress loss caused by friction between prestressed tendon and curved duct for the design of prestressed concrete structure. Formulas of normal pressure between prestressed tendon and curved duct and tension of prestressed tendon are derived based on the Hertz contact theory. And also the results come from experiments, derived formulas and current norms are compared in three cases.
