Abstract

In a prestressing strand for use in stressing a concrete structure, having a central core wire and a plurality of outer wires extending helically around the core wire the helical pitch length (S) of the outer wires is chosen to be between 20 and 150 times the maximum diameter of the strand. This strand is found to give more accurate stressing, especially where the conduit in the concrete for the tensioned wire is curved.
