摘要：The strength and strain relations of characteristics of the layers in multilayer wall structures made of concrete of different strength are presented, the dependence of the stress values in the layers on the operating conditions of the structure is revealed. On the basis of the principle of strain compatibility of concrete and reinforcement, the estimation of the stress-strain state of multilayer wall panels is done taking into account the conditional concentrated shears in the joint between concretes. A calculation method is proposed, which is based on strains during the combined action of torque and bending moments of three-layer reinforced concrete elements with rectangular section in the stage of working with cracks.
