An analytical modelling was performed using the finite-element method with the commercially available "ABAQUS" software. A shell element was used to model the concrete deck, steel webs, bottom flanges, and end-diaphragms. A three-dimensional beam element was adopted to model the top flanges, cross-bracings, and top chords. The multi-point-constraint option in the ABAQUS software was used between the shell nodes of the concrete deck and the beam element nodes of the steel top flanges, thus modelling the presence of shear connectors. Extensive parametric study, using the finite-element modelling, was conducted, in which 50 prototype bridges were analyzed to evaluate their load distribution factors for bending stress and shear under dead load and truck loading conditions. The span length of prototype bridges ranged from 20 to 100 meters, with two to four lanes. The number of steel boxes ranged from 2 to 4 in the case of two lanes, 3 to 5 in the case of three lanes, and 3 to 6 in the case of four lanes. The span-to-radius ratio was taken as 0, 0.4, 1, 1.4, and 2 for selected prototype bridges. The key parameters considered in the study were: number and stiffness of cross-bracings and top-chord systems, number of steel boxes, number of traffic lanes, bridge aspect ratio, and degree of curvature.
