Experimental Investigation on the Mechanical Properties of a Noval Bond-Type Anchorage for Carbon Fiber Reinforced Polymer Tendons
In order to effectively alleviate the stress concentration phenomenon of the inner-cone bond type anchorages and improve the ultimate anchoring capacity of the anchorages, a new kind of arcuate-cone bond type anchorage for carbon fiber reinforced polymer (CFRP) tendons was designed. The stress distr...

| description | In order to effectively alleviate the stress concentration phenomenon of the inner-cone bond type anchorages and improve the ultimate anchoring capacity of the anchorages, a new kind of arcuate-cone bond type anchorage for carbon fiber reinforced polymer (CFRP) tendons was designed. The stress distribution curves, load-slip curves and failure modes of anchorages are obtained by tension test of a group of innner cone and arcuate cone anchors with different parameters. According to the test results, the influence of anchorage types, inclination angles and radius of arc on anchorage performance is analyzed. The results show that ultimate anchoring capacity is directly proportional to the slip between anchor cup and grout during loading. The slip of arcuate cone anchorage is larger than that of inner-cone anchorage, and the anchor with smaller inclination angles of anchor cup slips larger. The ultimate anchoring capacity of the novel arcuate cone bond-type anchorages is larger than that of the traditional inner cone anchorages, and the phenomenon of stress concentration on the surface of CFRP tendons is effectively alleviated by using arcuate cone anchorages. |
