| Abstract: |
The ultimate stress of external tendons sometimes controls the prestress design of a bridge. The ultimate stress of an external tendon can be expressed as the addition of the effective stress of the tendon and a stress increment in Ultimate Limit State. The effective stress is closely related to the stress limitation of the tendon in Serviceability Limit State. Theoretical research and experimental investigation were made at the Department of Bridge Engineering of Tongji University in order to get reasonable stress limitation of external tendons and make recommendation for bridge designers. |
