Investigation of mechanic performance of hybrid structural element produced using glass fibre reinforced plastic (GFRP) composite and concrete

The use of Fiber-Reinforced Plastic composite materials in the construction sector has been growing rapidly in recent years. One of the increasingly widespread use of fiber composites is Pultruded Glass Fibre Reinforced Plastic (GFRP) materials. Developing production techniques combined high tensile strength, lightweight and non corrosive properties allowed GFRP to become a competitive alternative to traditional structural materials. Having resolved fundamental manufacturing constraints through the development of the pultrusion process, the mass adaptation of GFRP sections as primary load bearing elements have been used in a number of civil engineering applications. In recent years the use of GFRP composites with concrete caused Hybrid designs, one of the subjects showed great interest of researchers.In this study, compressive strength and flexural properties of hybrid use of GFRP profile with concrete have been investigated. GFRP box sections of the concrete placed in plastic form, creating hybrid structure elements, the experimental and theoretical studies have been conducted on the material. Properties of GFRP profiles were determined, which are produced with different strength of concretes produced compressive and flexural behavior of Hybrid material were investigated. Hybrid material, which are components of concrete and GFRP profiles were determined and material behavior of GFRP profiles were investigated. Theoretical studies on hybrid beams made evaluating the validity of a good fit were obtained. As a result of studies, Hybrid design has several advantages, as well as being, it has superior physical and mechanical properties according to component materials were determined.
