Dennis, In regards to the discussion on plywood shear walls deflections, as far as I know there is no universally accepted design or analysis procedure (that is accepted by the structural engineering community) to compute the deflection of vertical wood frame shear wall elements. However, there are a number ot "sophisticated" finite element programs that offer the possibility of predicting deflections analytically by using shear elements in conjunction with column elements to approximate the behavior of a wood frame shear element. Although these methods/techniques have been used in research, they have not been successfully proven in the design environment. My recollection is that Dames and Moore was working on something like this on the Northridge Meadows Apartments failure analysis, but I'm not sure about the results or their conclusions. It is, no doubt, a very important problem that needs further attention from the research community. In my research with concrete shear walls, I do think that a simple shear wall element for application on wood shear walls is possible with current technology. Hope this adds useful information to your inquiry. Sincerely Professor Dilip Khatri, P.E. Cal Poly, Pomona DKHATRI(--nospam--at)aol.com ...
