Steel cable specification
Steel cable specification
(OP)
Hello. I'm doing some research on the tower of the Montreal Olympic Stadium and came across a specification I haven't been able to decipher: "Freyssinet 24T/15". This is in reference to the type of post-tensioned pre-stressing steel cable used to support the structure. The specification was listed in the June 3, 1976 edition of New Civil Engineer. What does this specification refer to? The cable's ultimate stress? Its diameter? Any help would be greatly appreciated.
Thanks very much!
Thanks very much!

24 means the number of 7 wire strands. 15 means the 7 wire strands are each nominally 15mm diameter.
so the specification is that each tendon is made from 24 strands. Each strand is made from 7 x 3mm wires which form a strand of nominal 15mm diameter.
