<< A light-frame structure, with plywood shearwalls, does not have sufficient
lengths of tributary shearwalls (Li), within the 'wall-line' being
to comply with the prescribed height/length ratios for plywood shear walls.
May the bases of the Li be elevated above the finish floor to attain the
height/length ratio? If so, must all Li within the wall-line be the same?
Thanks in advance.
Not clear about your configuration, but you can measure the height of a
plywood shearwall from bottom of an opening to the top of the same opening as
long as you can take care of the resulting axial loads at the panel edges and
transfer them to the adjoining sheathed (top and/or bottom of opening) wall
panels. Just like a masonry or concrete wall pier analysis.
