Nonlinear fracture mechanics has been used for simulating the load-carrying behavior of steel fiber reinforced concrete floors on elastic bedding. In a numerical parametric study, influences of the fiber content, the slab thickness and the soil stiffness on the structural response of the slab under both service and ultimate conditions were studied. The material properties adopted for the numerical analyses have been de- termined by mean of wedge splitting tests. Results of structural tests available in the literature are in good ac- cordance with the simulation results. Furthermore, experimental observations regarding the influence of plas- tic and glass fiber reinforcement on early age cracking are presented.
