PROBLEM TO BE SOLVED: To firmly connect a cylindrical anchorage body formed of metal with a tendon inserted in a hollow hole of the anchorage body.SOLUTION: A thread 22 is provided at an end part 21 of the tip side of a tendon 1 in an outer circumferential surface of an anchorage body 2, and a holding part 23 is formed which can transmit a tensioning force to a structure while the tensioning force is introduced into a tendon. A cross section reduction part 26 with a reduced cross section is provided at the side with the tendon extended from the holding part. The cross section reduction part sets a cross section of the cross section reduction part and a range of the cross section reduction part in the axial direction so that a tensile stress intensity in the axial direction acting on the cross section reduction part reaches the yield point, while the tensioning force smaller than a breaking strength is introduced into the tendon. |
