| Summary: | This paper presents a part of the results from an experimental study of strain distribution
on reinforcement of concrete beams reinforced with glass fiber-reinforced polymer (GFRP) bars.
Under static loading conditions, eight concrete beams reinforced with GFRP bars were tested and as
comparison eight beams with steel reinforcement were also tested. All of the beams were prepared
with varying ratios of longitudinal reinforcement bars and stirrups. The effect of shear spaneffective
depth ratio on strain distribution of longitudinal reinforcement was also observed.
Furthermore, the behavior of strain on stirrups due to different materials of longitudinal
reinforcement was also discussed in this report. The test results show that the ratio of longitudinal
reinforcement significantly influence the strain distributions on reinforcement where the beams with
higher ratio exhibit higher strain. Moreover, it was also obtained that the different types of
longitudinal reinforcement considerably influences the strain behavior on stirrups as higher strain
was observed in beams reinforced with GFRP bars. |
