THE EVOLUTION OF A NEW HIGHWAY BRIDGE LOADING STANDARD FOR INDIA

The object of this Paper is to make a critical study of the present I.R.C. bridge loadings and to evolve a simplified new loading standard for India on a rational basis. Firstly, the historical background of highway bridge loadings is given and the I.R.C. loadings are compared with some of the typical loading standards of other countreis in terms of the maximum bending moment and shear force for simply supported spans upto 100 metres. The drawbacks of the loadings being followed in India are then brought out and the need for a revision of these is established. Finally, a revised standard based on a model of actual vehicular loading is evolved. The new loading consists of a uniformity distributed loading (the values of which, for different spans, are given by a simple formula) and a knife edge load. A tandem axle load is also specified for the design of small span members and for checking local effects. The main rules governing the application of these loads are given and the advantages of adopting the new loading standard are discussed.
