![]() ![]() To meet the needs of modern infrastructure, new innovative materials and technologies have started their way in the construction industry. The study showed that GFRP bars can be considered as load bearing longitudinal reinforcement of concrete columns and ignoring their effect is not necessary. Using the model, a parametric study was performed on the effect of eccentricity, reinforcement ratio, and concrete strength, which confirmed the capability of GFRP bars to sustain high strains without reaching the compressive strain capacity of the bars. The model considered both material nonlinearity and geometrical nonlinearity. In addition, an analytical model was developed and verified against the experimental test data. The experimental program showed no crushing of GFRP bars at peak load and the corresponding strain did not reach 50% of their crushing capacity obtained from material test. Three eccentricity to width ratios of 0.1, 0.2, and 0.3 were considered, where the eccentricities applied symmetrically at both ends of simply supported columns. The specimens were tested under concentric and eccentric compressive load up to failure. The experimental program consisted of fourteen 500 mm-long specimens with a square cross-section (150 Â 150 mm) including nine GFRP reinforced (6#5) and five plain concrete specimens. This paper presents experimental and analytical studies on short concrete columns reinforced with glass fiber-reinforced polymer (GFRP) towards characterizing compressive behavior GFRP bars. The flexural strength of unreinforced concrete is four MPa and bolstered concrete with GFRP rebar, specifically sand lined GFRP RC show off flexural power is 13.7 MPa as end result to growth bonding with concrete and higher pressure is 10.5 MPa at 28 days than that of metal strengthened concrete at the expense of flexural modulus. The compressive electricity was inside reasonable variety of concrete is 25.36 MPa. The end result show the tensile energy of GFRP rebar is 595 MPa and bend energy is 750 MPa. %) similarly disbursed with specific distances inside the mold. The fee of extent fraction of GFRP and metallic rebars in the strengthened concrete become (5 vol. The guidance of concrete samples (unreinforced concrete, clean GFRP strengthened concrete, sand covered GFRP bolstered concrete and metal reinforced concrete) with constant ratio of substances (1:1.5:3) and 0.5 W/C ratio had been completed at two curing a while (7 and 28) days in ambient temperature. Then, the mechanical characterization of bolstered concrete with GFRP rebars are done and compared with that of steel rebars. GFRP bars are increasingly used rather than steel bars to solve corrosion problems in reinforced concrete systems. GFRP bars have strong resistance to corrosion. GFRP rebars have diameter 12.5mm this fee is equal to 0.Five inch it's most 7 GFRP surfaces are changed by the inclusion of coarse sand to increase the bond power of rebars with concrete. Synthesis of GFRP rebars by using the usage of the longitudinal glass fibers (reinforcement material) and unsaturated polyester resin with 1% MEKP (matrix fabric) thru manual method. GFRP has been confirmed to be the answer as a primary improvement in bolstered concrete technology. The in this examine the use of GFRP bars and urban adherence were investigated. Pultrusion system is a verified production approach for acquiring lengths of high exceptional GFRP that used inside the production as a primary or secondary load bearing factors. They are synthetic the usage of various manufacturing methods. Glass fiber reinforced plastic (GFRP) are the sort of FRP kinds. Constructing cubes and beam through the usage of steel bars and additionally via the usage of FRP bars is executed and also comparing the effects acquired by using metallic sections and FRP sections with the aid of taking checks like tensile check, flexural test, compression take a look at, and so forth is finished. To maintain the identical quality of concrete during the examine, numerous take a look at specimen had been forged and trendy check like compression check, spit tensile check, modulus of rupture and modulus of elasticity on hardened concrete have been performed, confirming to Indian standards. In this experimental examine, concrete confirming to M20 grade is used. ![]()
