Abstract

The paper presents the developed method for calculating the contour-supported slab of self-stressed concrete. Reinforced concrete slab on the tension cement replaces the traditional construction of the bridge. In this article, in order to exclude reinforcement, the problem of determining the stress-strain state of self-stressed concrete slabs supported along the contour is considered. The values of stresses in the upper and lower faces of the concrete slab, as well as the bending moment in the middle section of the slab
