Короткий опис(реферат):
After reviewing the many reinforcement schemes, their inadequacies include the impossibility of efficiently unloading the compressed zone of the beam concrete, which significantly affects the stiffness and bearing capacity. The work is devoted to the determination of the parameters of strength and deformability of reinforced concrete beams, reinforced by a longitudinally transverse external system and a pressed reinforced concrete element in a compressed zone. As a result of the experiments, the physical and mechanical properties of concrete and reinforcement are discovered and, based on the obtained results, their final class is determined. During the experiments, control over the moment of crack formation and the development of cracks is carried out, and also the concrete deformations and deflections of the beams are determined.
