Abstract:
Presents an analytical investigation on the behavior of reinforced high-strength concrete slabs. A plasticity-based concrete model is used for the finite element analysis. An eight-node quadrilateral shell element with a reduced 2 x 2 Gaussian integration over the element plane and nine-point Simpson-type integration through the element thickness are employed. A suitable post-cracking tensile model of reinforced high-strength concrete is utilized, based on the fracture energy of high-strength concrete recorded from stress-displacement curves (stress-crack width curves). The validity of the developed model is then established by comparison with the results of reinforced high-strength concrete slabs. Finally, the behavior of such slabs is examined through a parametric study. The sensitivity of the material model to different material properties and edge restraints is also documented in the parametric study.
