CFS - X-Braced Strapped Shear Wall Uplift - Again
CFS - X-Braced Strapped Shear Wall Uplift - Again
(OP)
I have had this discussion before and it seems that some engineers take 1/2 the DL of the wall and other take the stud spacing, but I had a more direct question on an alternate method which uses a beam on elastic foundation (BOEF) approach.
Attached is a snippet from a good book on general engineering. They go through an example of the BOEF for a wood shear wall. They use the bottom plate of the wall above, the rim joist and the double top plate of the wall as the beam all added. Then to find the spring stiffness of the foundation (i.e. the wall studs) they use Eperp x A.stud / thickness of the double top plate. I don't completely understand the last part. Why not take E.parallel x A.stud / Length of the stud? Or add the two in series?
I don't believe I am violating any copyright laws but if someone knows otherwise please let me know.
