RESEARCH PROGRESS ON SHEAR STRENGTH OF CONCRETE BEAMS REINFORCED WITH FRP REBARS AND STIRRUPS

Abstract

Abstract: Fiber reinforced polymer (FRP) attracted wide attention in civil engineering field worldwide as a new type of high performance reinforcement for concrete structures. Shear strength of FRP reinforced concrete beams is effected by the unique characteristics of FRP rebars and FRP stirrups. Based on a number of experimental researches, several codes and design guidelines from different countries have provided computing equations of shear strength of FRP reinforced concrete beams, including Chinese GB 50608—2010, Japanese JSCE 1997, British BISE 1999, Italian CNR-DT 203/2006, American ACI 440.1R-06, and Canadian CSA.S 806-12. In order to evaluate the reliability of these equations, the computing results from these codes were compared with experimental values obtained from 33 experimental beams.

Key words: fiber reinforced polymer, concrete beams, FRP stirrups, shear strength, experimental data, code equations
