Wire Cross Bracing

Wire Cross Bracing

Wire Cross Bracing

(OP)
I am looking at using wire cross bracing in a structure I am currently designing in order to keep the weight down.

I have never used wire for bracing before as its always been steel flats or angles.

I will have to tension the wire up to counter any elastic effects under tension.  I can assess how much extension I expect to get under a specific tension but I'm not really sure how much tensioning force I need to set within the wire.  Does ayone have any guidance that may prove useful?

RE: Wire Cross Bracing

Are you considering one strand of wire, or is it wire rope made from numerous smaller strands?

I was considering small diameter multi strand wire.  But to make my life simple I have adopted steel flats instead.

Thanks for your attention.

RE: Wire Cross Bracing

Go to thread507-151844 and download "Wire Rope Engineering Hand Book" from my web site. Don't let the name mislead you, this book not only covers the "big" ropes, say 3" diameter, but also address sizes all the way down to so-called "aircraft cable", 1/8" diameter or less.

Page 29 (Stretch of Wire Rope) and page 30 (Approximate Moduli of Elasticity) are good places to start. Page 6 (Selecting Wire Rope), page 36 (Stresses in Guys), and page 56 (Wind & Ice Loads) may also be helpful.
