Cable Suspension Bridge - Support of Continuious Cable at top of Tower
Cable Suspension Bridge - Support of Continuious Cable at top of Tower
(OP)
I'm currently working on a suspension bridge where the main cable will go over the top of the tower, then continue down to the rock anchor foundation, in once continuous piece.
I have previously completed work where cable size was critical compared to sheave diameter (d/D ratio) to ensure stress in the outer fibers of the cable was not exceeded.
My question really is since the cable is no longer bent at a 90 degree angle (Actually closer to 30). Is this still a major issue with ensuring cable life span. I would like any reference material for the reduced angle anyone might know of.
I'm looking to accomplish something like the link below, but with a much smaller cable (2 1/2" Diameter) i'm wondering how complicated this assembly will need to be.

Does anyone have any experience or reference tables for this application?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
