Abstract

On the basis of deformational design analytical model of the cross section and block model of reinforced concrete element, a new analytical model is proposed by the authors. This model takes into account the work of tensioned concrete between cracks by applying additional stress in the reinforcement (steel bars) due to the difference in relative deformations between the tension reinforcement and concrete during the formation of a crack.

The developed model of analysis of reinforced concrete with cracks makes it possible to obtain the parameters of stress-strain state af the element in any cross-section along the length under the action of a bending moment and a longitudinal force.
