ABSTRACT:
A stressed reinforcing tendon for a structure has at least one stressed elongate element and an anchoring body in said structure to which said element is anchored by means of an anchoring device e.g. a wedge, button head or nut engaging the element so as to transmit stress in the element to the anchoring body. To overcome a potential weakness at the connection of the element to the anchoring device, there is a secondary load transfer element secured to the stressed element at a stressed portion thereof and secured to the anchoring body to relieve the said anchoring device of part of the stress being transferred to the anchoring body. The secondary element may be a tube secured to the stressed element by cementing material.
