| Abstract: | he research results about the unbonded, prestressed tendons and its application for the Yonghe cable stayed bridge in Tianjin were presented. An esperimental study on friction, slide and fatigue was carried on in the laboratory. It was proved that the unbonded, prestressed tendon has a number of advantages and is reliable in the post-tension bridge construction. |
