Abstract

The application of the limit equilibrium method to the calculation of reinforced concrete slabs allows us to obtain fairly simple expressions of the bearing capacity for various loading schemes. Usually, plates are calculated in a kinematic way, which consists in considering a set of possible destruction schemes, of which the one corresponding to the minimum load obtained from the equality of virtual works is taken as the calculated one. The reality of the schemes under consideration and, in particular, the calculated one is important, since otherwise the load-bearing capacity will be reduced.
