Elastic-Plastic Slabs on Elastic Foundation

A method of analysis and design of rectangular and circular elastoplastic, reinforced concrete, and slabs resting on a Winkler-type foundation is proposed in this paper. The method is an application of the yield-line theory of structures and gives upper bounds of the true limit loads. It is very simple and flexible so that realistic slab and loading configurations can be easily accounted for. The results of the method for a circular, centrally loaded slab agree with the ones reported by other researchers for a Winkler foundation, while of much interest is the comparison with the results for an elastic half space.
