Radius of curved bridge, skew angle, bending moment, longitudinal stress, deflection, torsion.

For the purpose of the parametric study, six box girder bridge models with constant span length and varying curvature and five models with varying skew angle and thirty model for combined effect. In order to validate the finite element modelling method, an example of box girder bridge is selected from literature to conduct a validation study. The example box girder is modelled and analysed in SAP 2000 and the responses are found to be fairly matching with the results reported in literature. For the purpose of the parametric study, the forty two box girder bridges are modelled in SAP2000. The span length , cross-section and material property remains unchanged. The only parameter that changes is the radius of curvature and skew angle. The cross section of the superstructure of the box girder bridge consists of single cell box. The curvature of the bridges varies only in horizontal direction. All the models are subjected to self weight and moving load of vehicle. A static analysis for dead load and moving load and a modal analysis are performed. The longitudinal stress at top and bottom of cross sections, bending moment, torsion and deflection are recorded. The responses of a box girder bridge curved in plan are compared with that of a straight bridge.
