Abstract: A method of applying a metal sleeve to a concrete reinforcing bar by introducing between opposed surfaces of the sleeve and the bar, particles having a hardness greater than that of the bar and the sleeve and then compressing the sleeve on to the bar with a sufficient force to cause the particles to bite into and grip both the bar and the sleeve.The metal sleeve may be provided as having on its internal surface particles of the foregoing properties. The swaged connection is achieved by carrying out the foregoing method. The invention also contemplates a concrete reinforcing bar with the swaged connection.

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.
