Abstract

Analysis and design of modern intersections requires the utilization of slab bridges of different kinds of geometry with various boundary conditions. A number of methods for deck analysis are evolved in past 30 years. The Grillage Analogy method is the most widely used Computer-Aided method. It is not only reliable but accurate for different types of bridges. The gird is formed by constituting the designed arrangement of structural members connected together at discrete nodes. It also works absolutely fine when it comes to heavy skew, isolated supports and edge stiffening. The bending and torsional moments are related to the deformation of beam elements with two ends through their torsional and bending stiffness. The present study reports the major variations that arise in the distribution of Shear Force, Bending Moment and Torsion due to the change in skewness in Composite I-girder bridges. It also studies the torsional and Non-Torsional behavior of I-girders. The behavior of bridge decks are researched extensively under different loadings.
