Abstract

The article presents the results of experimental studies of continuous reinforced concrete beams with combined reinforcement of composite and steel reinforcement of the stretched zone above the intermediate support with a different ratio of the ultimate tensile forces in composite and steel reinforcement. A picture of cracking in the zone above the intermediate support and in the span of experimental beams is obtained, the nature of their destruction, deformation features are determined, experimental dependencies "span bending moment – deflection" are constructed. The features of deformation of the stretched zone above the intermediate support of the beams are revealed, experimental dependences "support bending moment – angle of rotation" are constructed. Graphs of changes in tensile forces in steel and composite rods in the stretched zone above the intermediate support are obtained.
