Combined soil foundation analysis based on ultimate limit state

The paper defines an updated method for “soil – reinforced concrete foundation” calculation that takes into account their mutual interaction. In this method, both the foundation structure and footing are represented by a rigid-plastic model, which makes it possible to determine bearing capacity of system. This eliminates possibility destruction from punching exhaustion its capacity. It further presents results test conducted authors at Novocherkassk School Soil Mechanics Research validate theoretical calculations attained with use proposed as well tray testing models. modernized gives values close experimental studies. discuss challenge determining strength sand base, is known affect load-bearing capacity, propose solution uses piecewise linear limit line shear soil has been developed in attempt increase accuracy calculations.
