Abstract: In order to improve the performance of bond-type anchorage systems for CFRP bars, the influence of bonding medium, different surface shape of CFRP bars, anchor length, anchor end treatment on the anchorage performance are studied by static test. Test results show that epoxy structural adhesive anchorage properties of CFRP bars is better and expansion concrete is poor in the same situation. The surface shape of CFRP bars is significant to the anchorage performance. Further, the anchorage performance of epoxy film adhering sand is the best and polishing processing is the worst. 5mm and 7mm light round bars are recommended epoxy film adhesive sand. When anchoring length is 250mm, anchorage performance is the best. For 8mm and 16mm threaded bars, when epoxy sticky sand, anchoring length of 250mm and 330mm, it can give full play to the performance of the material.

Key words: CFRP bar, the anchorage performance, efficiency
