Abstract

Abstract

Due to the large size of the existing fiber reinforced anchorage is not conducive to engineering application, a new type of multi-cone anchorage structure was proposed. Its outer diameter is small, and the extrusion stress of multi-cone adjustable tendons can reduce the extrusion stress concentration at the loading end. Static tension tests were carried out to verify the effectiveness of the multi-cone anchorage. The experimental phenomena, anchorage efficiency coefficient and the extrusion stress at the loading end of the tendon were analyzed. The results showed that no slippage occurred in the multi-cone anchorage structure, and the anchorage efficiency coefficient reached more than 90%, which met the requirements of the cable anchorage design standard; the circumferential stress of the anchorage could reflect the radial extrusion stress of the internal tendons, and the difference between the circumferential stress of the two inner cones was not significant, which indicated that the new anchorage could effectively reduce the extrusion stress concentration of the tendons at the loading end of the anchorage.
