Study on shear resistance of fiberreinforced polymer-reinforced concrete beams

Abstract

This article is aimed to investigate the shear resistance of the beams reinforced with fiber-reinforced polymer stirrups. Together with theoretical analysis of the existing shear resistance provisions in design codes and literature, an experimental research was performed. During the experimental investigation, four doubly reinforced rectangular concrete beams were designed, produced, and tested to failure. A new analytical calculation method (including, but not limited to statistical validation) to investigate the shear response of fiber-reinforced polymer–reinforced concrete beams has been developed. A database with 102 beams was compiled, in order to evaluate the guideline provisions and proposed analytical calculation method. The experimental results were compared with theoretical results obtained by the proposed analytical calculation method. Correlation between analytical and experimental results is more accurate than using the existing provisions in design codes and literature for fiber-reinforced polymer–reinforced concrete beams.
