cable stayed bridge standards
i anticipate to soon begin a project on a small cable stayed footbridge.
does anyone know of a standard for cables or strand in cable stayed bridge applications? or perhaps a more general standard or reference literature that would contain information on safety factors for cable?
thanks so much.

try mark ketchum's web site or at least ask him. he is a great bridge designer and i have lots of respect for his expertise. his web site is
the american iron and steel institute published book called "manual for structural applications of steel cables for buildings" in 1973.  i don't know if they ever updated it or abandoned it.  it was somewhat helpful.
you might try their website:
you might also try dsi:
communication tower manufacturers such as pirod and rohn list breaking strengths of ehs and bridge strand cables in their catalogs. i don't know about bridge applications, but in telecommunications the eia/tia standard requires a factor of safety of 2.0 for guys and components.
here is some information from the federal highway administration.
i worked on the design of a short span cable-stayed bridge four years ago. bethlehem steel/williamsport wirerope works provided us with catalogs for strand, rope, and socket details. (i assume they're still in business). they're in williamsport pa; 570-326-5146.
also, you need to consider corrosion protection. if you're going to have exposed strands you'll need to select from class a, b, or c galvanizing. and remember to find out about the lead time for strand fabrication and galvanizing.
