| Abstract: | The anchorage zone in concrete box girder is one of the key structural components of cable-stayed bridge. The stay cables of Sanxianzhou bridge are longitudinally inclined in single plane, but laterally each cable composes of twin cables spacing 1.2 meters. The twin-cables are anchored in a concrete brick set in the middle box. The local stress distribution of anchorage zones and the transfer of cable forces are analysed by modern finite element method .The result shows that huge cable forces cause big transverse tensile stress in the deck, and the vertical components of cable forces are transferred by the webs and the cross slab fixed with the anchor brick. |
