Non-linear analysis of reinforced concrete slabs

Synopsis The paper describes the formation of a theoretical model which aims to describe the behaviour of a reinforced concrete slab throughout the whole of its loading range from initial loading to ultimate collapse. The model is based on the use of anisotropic finite elements, and a successive approximation technique. It synthesizes the section properties ofa slab from fundamental properties of the concrete and reinforcing steel. Moments, deflections and crack patterns are produced. The use of the model is illustrated by the analysis of a slab: the results of this analysis are compared with experimental results.
