Re: cable x-bracing?

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Karen,
 
Isn't cable quite a bit more flexible than solid steel?  It seems that sizing would need to be based on displacement control rather than strength -- especially if you are dealing with a rigid diaphragm.  Cable assemblies are unconventional in residential construction -- it may be hard to find a residential contractor who is familiar enough with it, and you may need to have more-than-ordinary involvement in the construction process to be sure that the frame is properly built.
