A study of existing research shows a need for an investigation of the bond properties of anchorage systems for glass fiber-reinforced polymer (GFRP) bars including mechanical anchor heads and bends. In this research program, the standard pullout test procedure was modified, which improved testing efficiency, accommodated bent bar tests, and reduced the variability of concrete properties across test specimens. Based on this experimental work consisting of a total of 72 specimens, it was concluded that the surface profile of GFRP bars influences only the post-peak phase of the bond stress-slip curve. It was also found that GFRP bars with anchor heads still require a considerable bonded length to develop the bars’ full strength.
