The paper presents an analytcal investigation of the behavior of reinforced high strength concrete slabs. A plasticity-based concrete model is used for the finite element analysis. The details are described of the study in which a suitable post-cracking tensile model of reinforced high-strength concrete was used based on the fracture energy of high strength concrete recorded from stress-displacement curves. The validity of the model is then established by comparison with the test results of reinforced high strength concrete slabs. The behavior of such slabs is examined through a parametric study. The sensitivity of the material model to different properties and edge restraints is also demonstrated.
