| Abstract: | The characteristics of concrete beams reinforced with glass fiber polymer bars were investigated experimentally.Based on these test results the effects of bar's type and reinforcement ratio on the crack spacing,crack width as well as the deflection of the beam are studied in detail.A method for calculating the crack width and deflection of this kind of beam is suggested. |

| Keywords: | glass fiber reinforced polymerbar concrete beam crack width deflection |
