Abstract In order to investigate the influence of main design parameters on anchorage performance and internal stress distribution of wedgebond anchorage for CFRP tendons, five groups of parameter tests on wedgebond anchorage were designed. The ultimate load, slip deformation of anchor ring and stress of metal sleeve stations were determined. The influence of design parameters on anchorage performance, the tress distribution and variation of metal sleeve were contrastively investigated through static loading testing. The results show that the anchorage performance with metal sleeve thickness of 2 mm, a wedge length of 65 mm, bond length of 500 mm is optimal. The anchor between wedge and metal sleeve is good without relative displacement. The tress distribution and variation of metal sleeve can reflect the internal stress distribution of anchorage, and the perk of stress curve indicates bonding failure between colloid and CFRP tendon near the observation point.
