Experimental and theoretical investigation of compositereinforced concrete beams

The use of new generation composite materials in the construction industry is increasing day by day as they are used in other sectors. Composite materials have effective properties such as high The use of new generation composite materials in the construction industry is increasing day by day as they are used in other sectors. Composite materials have effective properties such as high strength/weight ratio, non-abrasive structure, lightness, smooth surface structure, etc. Concrete is one of the most widely used building materials in construction because it has various advantages. Conventional concrete has strong compressive strength but weak tensile strength. Macro synthetic fiber has been used in conventional concrete to eliminate this weakness in tensile strength as well as improve the ductility of concrete. Within the scope of the study, the mechanical properties of concrete were investigated by performing the slump test, pressure test, splitting test, bending test, cube ultrasonic concrete test and Schmidt hammer test and using macro synthetic fibers. Corrosion of steel is known as one of the most prominent problems in construction. Today, GFRP (Glass Fiber Reinforced Polymer) reinforcements with high corrosion resistance, lighter than steel and high strength are used. In the second part of the study, a four-point bending test was carried out on reinforced concrete soils. Rectangular cross-section hybrid (steel-FRP-fiber) reinforced beams are designed. The cross-section of the presented study is 0.20x0.15m and 1.24m in length. In this experimental study, a total of 15 reinforced concrete beams were produced. The parameters of this study are: 0.4% and 0.8% macro synthetic lif by volume, steel reinforcement and FRP reinforcement. 6 of these beams are reinforced with CFRP (Carbon Fiber Reinforced Polymer). The experimental results were compared with the results obtained from the finite element model Abaqus program.
