Abstract

A numerical approach is developed here to evaluate the flexural and punching shear and capacities of two-way reinforced concrete plates. Inclusively, the approach analyzes the unrehabilitated two-way plates made of normal or high strength concrete. A special concrete constitutive model of concrete is introduced that consider biaxial state of concrete in a twoway plate as well as the confinement effect of steel plates for the rehabilitated slabs. The constitutive model of concrete includes defining the concrete properties in tension including pre cracking and post cracking properties of concrete. The theoretical approach is iterative incremental in nature bywhich the deformation characteristics of a slab is evaluated at each load increment until failure. A comparison between the suggested numerical approach and some of the available data of rehabilitated and un-rehabilitated normal and high strength concrete twoway plates shows a good agreement with respect to the deformational behaviour, the ultimate capacity and the mode of failure.
