left side of SW1 is transferred into SW2 by transfer diaphragm action. As an alternate, the
walls could also be designed using the cantilever wall method if the sill sections on the
right side of the full-height sections are utilized. The forces at the top of the sill sections
would have to be transferred into the full-height wall sections using transfer diaphragms,
as previously discussed. The headers at the second-floor and first-floor walls can act as
collectors to transfer diaphragm and wall shears into the shear walls, as required by code.
Gravity loads are ignored in this example to provide clarity in the method of determining
the wall shears. The sill sections below the opening will not be used.
Basic information (Fig. 11.6):
h = 8′-0″ wall height of irst- and second-loor walls
V r = 2000 lb shear force at roof
V 2 = 3000 lb shear force at second loor
L SW1 = 8′-0″
L SW2 = 12′-0″
