PARAMETRIC STUDY OF SKEW ANGLE ON BOX GIRDER BRIDGE DECK

Box girder bridge deck, is the most common type of bridges in world and India, it consists of several Slab or girders. The span in the direction of the roadway and connected across their tops and bottoms by a thin continuous structural stab, the longitudinal box girders can be made of steel or concrete. The Simple supported single span concrete bridge deck is presented in present study. Skewed bridges are suitable in highway design when the geometry of straight bridges is not possible. The skew angle can be defined as the angle between the normal to the centerline of the bridge and the centerline of the abutment or pier cap. Due to high traffic road can hardly modified in order to eliminate the skew. Therefore, considerable numbers of skew bridge decks are constructed. The skew angle effects on the behaviour of the bridge. Therefore, there is need for more research to study the effect of skew angle on performance of bridges. In the present study, the effect of change in skew angles with normal bridge is studied. Longitudinal moment, shear force, deflection and transverse moment are computed by modeling using STAAD-PRO with IRC loadings and results are compared.
