Re: Wood Shear Walls Bracing Masonry

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Barry:

I do not have anything to back up my answer to your question, but if I were
to guess, the reason wood shear walls cannot be used to resist masonry is
the difference in rigidities.

I believe that the masonry is so stiff compared to wood, that the wood shear
walls would deflect too much for the masonry.  In other words, the masonry
wall will need to deflect with the lateral resisting elements (masonry wall
is perpendicular to shear walls) and this deflection will cause the masonry
wall to fail in the out-of-plane direction.

If anyone knows the answer to this question, has a better explanation, or
disagrees, please respond.
