In the realistic non-linear analysis of reinforced concrete structures, it is important to consider the effect of material behaviour, such as concrete cracking and steel yielding, in detail. Such an analysis when carried out incrementally leads to realistic evaluation of deflections, stresses and strains over the whole range of loading up to failure. In general this kind of analysis is research rather than practical analysis orientated. A designer is particularly concerned to find out the ultimate load for a given structure, without going into too much detail. This work presents yield criteria developed for reinforced concrete inplane structures. The yield criteria were implemented in a finite element program to analyse such structures as an elasto-plastic material. Three reinforced concrete deep beams were analysed and the prediction of the present model was compared to the experimental and a detailed non-linear finite element results. It was found that the results of the present analysis were in good agreement with those obtained both experimentally and numerically using detailed nonlinear analysis by modelling reinforced concrete to consist of a series of steel and concrete layers in plane stress. However the deflection predictions of the present model were conservative as non-cracking assumption was made for concrete.
