Creep in Bridge Rope
Creep in Bridge Rope
(OP)
I'm looking for information that provides the estimated long-term creep in either Bridge Rope - 6x7 WSC or Bridge Strand (Class A coating). I have information that gives me the E, and the max. tensile strength of various diameters, but nothing on long term creep.
As in high-strength prestressing strand, there is a long-term loss of prestress due to relaxation of the strand. Looking for ways to estimate this for the rope or strand over time in similar fashion.

If you send me your fax number I can fax the graphs and data to you. My email : ribeneke@iafrica.com

Taking incurvation into account, 1.66 to 2 safety factors seem be the equivalent ones, by the same source. But you then need very accurately evaluate the stresses at details., one must infer from the difference of safety factors with or without.

Any other info on relaxation would be greatly appreciated.
