摘要：

Full-size　specimens　of　the　double-ball　anchorage　system　used　in　prestressed　concrete　structures　were　tested.　Its　performance　under　repeated　loads,　the　static　behavior　of　the　anchorage　ever　subjected　to　the　repeated　loads　and　the　influence　of　different　ranges　of　the　stress　fluctuation　on　its　performance　are　studied.　The　tested　results　are　shown　that:　the　double-ball　anchorage　meets　the　requirement　for　the　repeated　loading　tests　specified　in　the　code;　with　increasing　numbers　of　the　loading　cycles,　its　load-deformation　relationship　in　each　cycle　loading　behaves　nearly　in　linear-elastic;　over　the　repeated　loads　of　50　cycles　is　resulted　in　significant　changes　of　the　static　behavior　of　the　anchorage,　but　its　maximum　load-carrying　capacity　and　ultimate　deformation　capacity　are　not　decreased.
