is similar to that in fig3 however one pair of tendons 4c 4d is placed between the tendons 4a 4b of the other pair to prevent a possible generation of torsional moments in view of these two basic arrangement with four individual rectilinear tendons 4 there are other possibilities for the distribution of the end anchors 6 depending on the requirements and the load by multiplying the tendons the insertion of individual tendons located in the vertical plane v v and extending parallel to the long axis l l of the tie is also possible to reduce the number of end anchors it is known in prestressed concrete ties to use hairpin like reinforcing elements made up of two rectilinear tendons interconnected at one end by a curved part of bight 17 so that a single tendon unit is formed in fig6 9 a prestressed concrete tie is shown with a tie body 11 made up of two wide end support members 12 12 39 interconnected by a reduced width central section 13 with the tie body reinforced by tendons 14 of a hairpin like shape as in fig5 two tendons 14a 14b or 14c 14d constitute a pair with the tendons of each pair connected by a loop like bight part 17 the anchoring loops or bight parts 17 should extend at right angles to one another to the extent possible to diminish tensile fissure forces generated by the reversal of forced lines note fig8 the position of the bight parts 17 at the tie end 15 39 is shown in fig6 and 7 fig7 and 8 illustrate the course of the tendons 14a 14b and bight part 17 and 14c.
