| Description |
Over the years, different methods of analysis of bridge superstructures have been evolved and are being used. When considering the complete field of slab, pseudo-slab and slab-on-girder decks, grillage method of analysis seems to be completely universal with the exception of methods such as finite element, finite difference and finite strip. The grillage analogy method can be applied to the bridge decks having complicated features, and has proved to be reliably accurate for a wide variety of bridge decks. In this paper, formulations for automated analysis of continuous span I and T- girder bridge decks using grillage analogy have been presented. A computer program has been developed based on the formulations for automated analysis of continuous span I- and T- girder bridge decks of uniform and non-uniform cross-sections using grillage analogy. The program is capable of modelling the bridge deck as equivalent grillage, calculates member properties and distributes the dead load, live load and
moving loads as equivalent nodal loads. Different types of IRC loading were incorporated in the program and the program can also take the user defined loading. To demonstrate the efficacy of the method analyses have been carried out for different types of bridges including non-uniform girder bridges. The results are in good agreement with those obtained using finite element analysis.
