Buckling method for determining mechanical characteristics and properties of composite rebar

Abstract

This article presents the experimental values of the mechanical characteristics and properties of fiberglass rebars. The authors studied the work of rebars under the action of aggressive media and different temperature regimes. It was found that the optimum length for determining the mechanical properties of fiberglass rebar by using the buckling method are samples of 210 mm. When the temperature increases, rebar becomes more ductile, elastic modulus and strength of reinforcement significantly reduce.
