An anchor arrangement including: a hollow anchor arranged, in use, to be located to a first side of a structure; and the hollow anchor having a first end, in use, located at the first side of the structure and a second end opposed to the first end such that, in use, the second end extends towards a second side of the structure opposed to the first side of the structure; and the interior of the hollow anchor generally inwardly tapers towards the second end; a plurality of multi-wired tendons; end regions of the tendons are arranged, in use, to be located in the hollow anchor, within the hollow anchor adjacent wires of the end region of each tendon are in contact with each other along the majority of the extent of the end regions of the tendons, and the tendons are arranged, in use, to be inserted from the second end of the hollow anchor to locate the expanded sections in the hollow anchor towards the first end of the hollow anchor; characterised in that: at least some of the end regions of the tendons include an expanded section nearest the end of the tendon, the expanded section being spaced from the end of the tendon, the wires over a length of the expanded section being separated from each other such that they do not contact each other; and at least one tendon with the expanded section includes an end fitting arranged to constrain the ends of the wires of the tendon at the end of the tendon to remain in contact with each other; and the expanded section of adjacent tendons, when located in the anchor, are arranged to cooperate with each other to assist in resisting any force attempting to withdraw the tendons out of the second end of the anchor in a direction towards the second side of the structure. a hollow anchor arranged, in use, to be located to a first side of a structure; and the hollow anchor having a first end, in use, located at the first side of the structure and a second end opposed to the first end such that, in use, the second end extends towards a second side of the structure opposed to the first side of the structure; and the interior of the hollow anchor generally inwardly tapers towards the second end; a first end, in use, located at the first side of the structure and a second end opposed to the first end such that, in use, the second end extends towards a second side of the structure opposed to the first side of the structure; and the interior of the hollow anchor generally inwardly tapers towards the second end; a plurality of multi-wired tendons; end regions of the tendons are arranged, in use, to be located in the hollow anchor, within the hollow anchor adjacent wires of the end region of each tendon are in contact with each other along the majority of the extent of the end regions of the tendons, and the tendons are arranged, in use, to be inserted from the second end of the hollow anchor to locate the expanded sections in the hollow anchor towards the first end of the hollow anchor; characterised in that: at least some of the end regions of the tendons include an expanded section nearest the end of the tendon, the expanded section being spaced from the end of the tendon, the wires over a length of the expanded section being separated from each other such that they do not contact each other; and at least one tendon with the expanded section includes an end fitting arranged to constrain the ends of the wires of the tendon at the end of the tendon to remain in contact with each other; and the expanded section of adjacent tendons, when located in the anchor, are arranged to cooperate with each other to assist in resisting any force attempting to withdraw the tendons out of the second end of the anchor in a direction towards the second side of the structure. end regions of the tendons are arranged, in use, to be located in the hollow anchor, within the hollow anchor adjacent wires of the end region of each tendon are in contact with each other along the majority of the extent of the end regions of the tendons, and the tendons are arranged, in use, to be inserted from the second end of the hollow anchor to locate the expanded sections in the hollow anchor towards the first end of the hollow anchor; characterised in that: at least some of the end regions of the tendons include an expanded section nearest the end of the tendon, the expanded section being spaced from the end of the tendon, the wires over a length of the expanded section being separated from each other such that they do not contact each other; and at least one tendon with the expanded section includes an end fitting arranged to constrain the ends of the wires of the tendon at the end of the tendon to remain in contact with each other; and the expanded section of adjacent tendons, when located in the anchor, are arranged to cooperate with each other to assist in resisting any force attempting to withdraw the tendons out of the second end of the anchor in a direction towards the second side of the structure.
