Study on Placement of U Tendons in Box-Section Pylon of Cable-Stayed Bridge

Abstract:

Article Preview

Through the analysis of the stress distribution in anchorage zone of bridge pylon with different placements of tendon, the placement with the equal coefficient of anti-crack in both sides is proposed. At the same time, several models whose outsides are crossed by tendons at different angles are analyzed. Compared the corresponding cracking loads and cracking place of them, a reasonable angle range is obtained. At last, the vertical attenuation ratio of the prestressing in the anchorage zone under the tendon is analyzed to give the appropriate distance between the adjacent tendons.
