Abstract:
The article presents the results of experimental and theoretical studies of the resistance mechanism of T-beams made of heavy and light concrete, taking into account shear forces and deformations. Their behavior and stress-strain state after crack formation are analyzed. New data on the development of normal and tangential displacements in inclined cracks have been obtained. For the analysis of experimental data, a simplified approach was used, based on the implementation of the truss analogy model, taking into account energy methods and the revealed mechanism of engagement forces in inclined cracks of the beam rib. In the analysis, the conditions for the equilibrium of forces in the inclined section of the beam were used, taking into account the forces in the longitudinal and transverse reinforcement and the engagement forces.
