A pre-stressed concrete bridge is a construction structure that connects a place to another place that is made by giving a voltage opposite the voltage caused by an external load. The process of giving tension can be carried out before the concrete is printed (pre-pull) or after the concrete is printed (post-pull).On pre-stressed concrete bridges, the strength and reliability of a bridge are greatly influenced by the type and quality of the girder beam used. Structural analysis is carried out by calculating the initial prestressing force, determining the trajectory of the pre-stressed tendon, calculating the loss of pre-stressing, and controlling the stress that occurs in the cross section of the girder using strands of 12,7 0,5 STA 162. The purpose of this study is to plan pre-stressed concrete girder which refers to the Concrete Structure Planning for Bridges (SNI T-12-2004), and pre-stressed for bridges (SNI T-02-2015) with U-Box Girder type and VSL Standard. The analysis obtained, the use of tendons and strands were 8 tendons and 150 strands with loss of pre-stressed styles, namely anchorage friction of 46.31%, jack friction of 44.92%, elastic shortening of 41.85% and tendon relaxation of 33% and control deflection into a safe area.
