ABSTRACT
In the paper the mathematical model of the optimization problem of analysis for reinforced concrete plane frames, containing elastic-plastic and brittle elements, is proposed. It is assumed that the load varies randomly within the specified limits. The examples of the optimization problem formulation and calculation of stress-strain state of the frame up to failure, using finite-element software, are given.For citation: Alyavdin P., Bulanov G.
