Nowadays, the application of steel fibers in concrete has increased gradually as an engineering material. The knowledge is not only necessary to provide safe, efficient and economic design for the present, but it also to serve as a rational basis for extended future applications. In this study, steel fibre reinforced rigid pavements are analyzed for stresses developed due to Static loads & temperature differentials. All the models are generated and analysis is carried out using the ANSYS software. Comparison of curling stresses in SFRC with conventional concrete is carried out. Parametric study for the effect of change in slab length & slab thickness of pavements on curling stresses is also done. Curling stresses due to Linear & Nonlinear temperature distribution in top & bottom layer of SFRC pavement slabs are also calculated. Frictional stresses in SFRC due to uniform temperature differential are almost same as conventional concrete. Analysis results shows, SFRC develops more stresses as compared to conventional concrete & nonlinear temperature distribution develops more stresses than linear temperature distribution. SFRC pavements are analyzed for Single axle static load for varied thickness and subgrade. Results reveal that the loading stresses are higher, when the load is at the edge region.
