Abstract
Determination of the strength of concrete compressed with composite materials located in the transverse direction
Incoming article date: 05.09.2021In recent decades, composite materials have been widely used in the reinforcement and fabrication of reinforced concrete structures. However, the volume of experimental and research work in Russia is not large enough to determine all the possibilities and real effectiveness of composite materials in this area. This paper presents proposals for improving the methodology for calculating the strength of reinforced concrete flexible eccentrically compressed struts reinforced with composite materials in the transverse direction. The developed proposals are based on the results of experimental studies. The proposals were developed in the field of determining the additional compressive strength of concrete from the action of composite materials located in the transverse direction. The paper describes the shortcomings of the normative calculation methodology and developed a coefficient that corrects the formula for determining the resistance of concrete reinforced with composite materials Rb3.
