In this thesis, a theoretical investigation on the elastic behavior of straight and curved non-composite single-cell box girder bridges is presented. A finite-element analytical model, based on the commercially available "ABAQUS" software, was used for the analyses. A shell element was used to model the steel web, bottom flange, and end-diaphragms. A three-dimensional beam element was adopted to model the top flanges, cross-bracings, and top chords. An extensive parametric study, using the finite-element modelling, was conducted, in which 15 non-composite single-cell bridge prototypes were analyzed to evaluate their load distribution factors for moment, reaction, axial force and deflection under dead load conditions. The span length of prototype bridges ranged from 20 to 100 meters. The width of the cell was taken as 3.0, 3.8, and 4.65 meters. The span-to-radius of curvature ratio was taken as 0, 0.4, 1.0, 1.4, and 2.0 for selected prototype bridges. The key parameters considered in this study were: the stiffness of horizontal bracing at the level of top flanges, number and stiffness of vertical cross-bracing and top-chord systems, width of the cell, degree of curvature, and span length.
