Abstract: Solid deck slab bridges are simplest type of bridges adopted mostly for small span and are constructed with or without footpath. Different methods are developed for the analysis of solid deck slab bridges out of which Finite Element Analysis (FEA) and from conventional analysis side, effective width method (EWM) are popularly used. In this paper, a comparative study between FEA and EWM in the analysis of solid deck slab bridges with and without footpath for different loading conditions as per IRC 6 (2014) was done. The study shows that there is 10-45% variation in design forces. The study also reveals the effect of footpath on solid deck slab bridges for live load cases and brings out the conclusion that inclusion of footpath reduces the design forces by 10-30%.
