The results of the experimental research of the strength and deformability of normal cross sections of reinforced concrete beams reinforced in tension area with additional sheet reinforcement without the bond.
The method of experimental tests of reinforced concrete beams, strengthened additional prestressed reinforcement under load (at different levels of prestressing andactive load), with the corresponding control a strength of normal cuts and prestressed additional reinforcement.Developed and presented a program of experimental tests to assess strength parameterof normal cutsexperimental reinforced concrete beams,reinforced prestressed reinforcement under load. Based on the research program developed design prototypes and selected characteristics necessary materials.
