Influence of skew angle in the design of grids

In highway bridges the major challenge is to maintain the geometry, in order to supply a greater speed and safety, which indeed increases the demand of skewed bridge. The presence of skew angle makes the design very complicated and vague. In this paper the response of skew angle on the bending moments, torsion moments, stiffness and aspect ratio of bridge is being highlighted. And the design aspects are also discussed. Finite element analysis was carried out based on beams grillage model under Indian Roads Congress (IRC)-Class AA loading. This provides additional information about the response of the parameters for skew angles between O° and 45°. The responses of the parameters with reference to skew angle are discussed elaborately for the four different loading position considered in the analysis, such as Bending-Bending, Torsion-Torsion, Bending-Torsion and Torsion-Bending.
