ABSTRACT:
A method of coupling the strands 2, 5 of adjacent sections of a stressing tendon in a multi-span post-tensioned concrete structure comprises tensioning strands 2 of a first section of the tendon, anchoring the strands 2 in an anchorage member 1 using wedges 3, and then joining the strands 2 of the first section to strands 5 of a second section of the tendon in end-to-end relation by compressing metal sleeves 6 around the strands. The sleeve 6 may have hardened metal inserts 7. The outer strands 5 may be gradually directed inwards by a first collar 9 and a second collar 11 may be provided so as to gradually direct the strands 5 into a duct 10 for the second section of the tendon.
