Re: Tension Stress Graphs

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I believe that what you are being asked for is a graph relating tension
stress in the cable versus distance in the member.
In this graph you are able to relate:
1- Variation of stress in cable due to friction in duct and wobble of
cable.
2- Variation of stress in the stressing end due to seating of anchors.

This graph usually has only a theoretical merit, but allows you
finetuning of jack force values so you never exceed allowable cable
stresses  (0.70 ultimate strength) in the vicinity of the
anchorage/bearing plate assembly.

Please contact me for further comments.
