The Influence of the Rib Depth on the Tensile Properties of GFRP Bar

Abstract:

Different surface forms will have a huge impact on bond of GFRP rebar and concrete, and the ribs depth is the key factor that affects the bond with concrete, therefore, the surface forms and rib depth should be taken into account when GFRP bars are used as the structural reinforcement material. Based on two kinds of rib spacing and rib depth of GFRP reinforcement on tensile performance test, this article studies the different influence of ribs depth on the tensile properties and mechanism. Experimental results show that rib depth has distinctive impact for the GFRP tendons ultimate tensile strength, elastic modulus and ultimate elongation.
