Abstract: For placing a multiple strand cable under tension by successive tightening of the different strands by means of an individual jack, procedure is as follows: the first strand of the cable is tightened, called below "control strand" while keeping possible then measurement of the tension of this strand at any moment, then pulling a second strand until its tension is equal to that of the control strand, measured at the same moment, and then anchoring this second strand so stretched, a third strand is then tightened until its tension is equal to that of the control strand measured at the corresponding moment and then this third strand so tightened is anchored, and so on until the anchoring of the last strand, after which the tension then applied to the control strand is noted and, after having relaxed the latter and having freed from it the measuring means, this control strand is anchored while applying to it the tension thus noted.
