Seismic Retrofit of RC Members Using FRP with Very Low Young's Modulus
Abstract eng: This paper proposes a use of fiber reinforced polymers (FRP) with very low Young’s modulus to solve various issues of ordinary FRP’s. “Super Reinforced with Flexibility (SRF)” is a polyester fiber reinforced polymer which has 1/40 of Young’s modulus, 1/35 of tensile strength, 10 times larger fracture strain, and 2/3 of price compared to carbon fiber reinforced polymer (CFRP). SRF has potential to substitute CFRP for its high seismic performance and ease of construction. In an experimental program, two identical structural wall specimens with eccentric openings and five cantilever column specimens were constructed with and without SRF strengthening to study effects of SRF on the shear and confining mechanisms. Strengthened specimens showed larger shear strengths and ductility. Test results were studied to consider the resisting mechanism of concrete structures strengthened with SRF.
