Abstract: “The analysis of Reinforced Concrete (RC) structures by using finite element techniques takes great attentions through the last two decades. A lot of finite element packages like ANSYS, ABAQUS, COSMOS, Dyna-3D, and NASTRAN have been modified to be used in the analysis of different elements of RC structures. In this paper ANSYS finite element software was used to analyze the structural behavior of high strength RC slabs. The analysis of RC slabs was considered in three dimensions finite element analysis, where effects of material and geometric nonlinearities were taken into consideration to increase the accuracy of the results. Flexural capacity of RC slabs was measured experimentally and calculated analytically using ANSYS. Comparisons between experimental and analytical results were performed. Comparisons between typical cracks patterns and modes of failure were comparable.”
