Abstract
A cable anchorage anchors a cable, for example a stay cable having multiple strands (50), against a longitudinal tension force. The anchor block (11) of the anchorage includes multiple channels, through which the strands (50) are individually threaded. Once in position and tensioned, the space around the strands (50) in the anchor block (11) is injected with a liquid, such as a polyurethane, which subsequently sets to form a tough elastic bedding material (51) within the anchor block (11). The elastic bedding material (51) has a durometer at 23° C. in the range 10 to 70 Shore, so as to form bedding cushion extending substantially around the strand (50) in the strand-channel (6) along a bedding region (54) of strand-channel (6), the bedding cushion reducing the bending stresses in the strand (50) by absorbing bending stresses along the bedding region (54).
