Abstract
In this paper, test results of four glass fiber-reinforced polymer (GFRP)-reinforced concrete simply supported beams are presented. This experimental study aims at evaluating the bond-dependent coefficient (kb) and verifying its dependency on bar diameter and concrete cover in normal-strength concrete beams. Only deformed/ribbed GFRP bars were used as main longitudinal reinforcement in all beams. The beam specimens were 2,800 mm long 200 mm wide 300 mm deep and were tested in flexure under four-point bending configuration over a simply supported span of 2,400 mm with 200 mm overhang on each side. The test results showed that the bar diameter and concrete cover affected the crack width and consequently the value of kb. Also, the average kb was found to be 0.9 for ribbed GFRP bars which is lower than the current recommendations in codes and guidelines for deformed/ribbed FRP bars.
