    Question:In prestressing work, if more than one wire or strand is included in the same duct, why should all wires/strands be stressed at the same time?

     

    Answer:
    If wires/strands are stressed individually inside the same duct, then those stressed
    strand/wires will bear against those unstressed ones and trap them. Therefore, the friction of the trapped wires is high and is undesirable.
