| Abstract: | A perpetual downward deflection of Burri Bridge on the Nile River in Khartoum has taken place to the cantilever end of the main bridge. External pre-stress method is used to reinforce the bridge. In this paper, reinforcement principle, key points and management of construction about external pre-stress technology are introduced for the same style long span bridges. In order to evaluate the effect of this method, the static behavior of a T-shaped bridge reinforced by prestressed external tendons was analysed by finite element software. |
