Abstract (en)
A strand for prestressing of concrete components, which strand (10) is made up of at least one central wire (4) and of a plurality of surface wires (1) twined around it, the central wire or wires running substantially without spiral in the longitudinal direction of the strand. The cross sectional area of the central wire (4) has been shaped so, or the strand (10) contains a plurality of central wires so located and dimensioned, that the envelope (6) of the cross section of the strand is made up of a combination of sections of two circles (Y1, Y2) of different radii (R1, R2) and is thus not rotationally symmetric. <IMAGE>
