This final paper has the objective to perform the structural dimensioning of the passive reinforcement of the Superstructure and the Substructure of a highway reinforced concrete bridge with multiple longitudinal girders that total span is 120 m and the deck structure is 19,50 m, according to the prescriptions of the current Brazilian National Standards Organization (ABNT) and the current bibliography. In order to analyze the slabs, the Rüsch method was used considering the central slabs as isolated, with the continuity of the bending moments in the longitudinal and transverse directions. The Leonhardt method was used to analyze the bridge as a grid, with 5 (five) longitudinal girders that central spans are 30 m and the cantilevers are 15m, locked by 6 Cross girders at the central spans and 3 at the cantilevers. The Substructure are composed of 2 frames consist of Elastomeric bearings, pier cap, piers and strut girders. The structural dimensioning was performed considering only the Ultimate Limite States and the Ultimate Limite States of Fatigue, with the suggestion of quantity and diameter of reinforcement bars, attending all the proposed checks, through the software: AutoCAD, Excel, Ftool, PCalc e T-Rüsch.
