摘要
Abstract
Nine reinforced concrete (RC) beams strengthened with glass fiber reinforced polymer (GFRP) sheets and three control beams were tested. Four parameters considered in this experimental program included the concrete strength, the reinforcement ratio, the number of GFRP sheets, and the shear span ratio. It is shown that the application of GFRP sheets can increase the ultimate flexural capacity. The effect of the concrete strength, the reinforcement ratio and the number of GFRP sheets on load capacity is obvious. The shear span ratio can affect the failure mode of RC beams strengthened with GFRP sheets. A theoretical model for flexural behavior of the strengthened RC beam is also developed.关键词
