Abstract:

This paper aims at solving the difficulty in arriving the bending moment coefficients of bridge deck slab from cumbersome Pigeaud charts. In this study, the bending moment coefficient values from pigeaud charts are tabulated for different IRC (Indian Road Congress) classes of loadings using interpolation technique. For this study, IRC classes of loadings viz., Class AA tracked and wheeled, 70R tracked and wheeled, Class A and Class B vehicle loadings are taken into considered. A program using MATLAB software is developed to interconnect these tabulated bending moment coefficient values in the analysis of pre-stressed concrete deck slab. It is observed there is a good agreement between computational analysis and theoretical analysis. This study facilitates the analysis of pre-stressed concrete deck slab to be easier and systematic.
