Our office designs wood frame structures.  When we would do a rigidity
analysis, and allow Rho to exceed one, in some cases we found that by
reducing the number of shear walls we could reduce the Rho factor.  A very
fine tuned code compliant design.  Redundancy.  I draw a violin.  It is
built with a chain saw.

Mr. Greenlaw notes:

"...My own examination shows that the present Rho factor procedure for
shear walls completely missed the point on obtaining redundancy; instead it
penalized lack of lineal feet of panel, regardless of stress per foot or
number of panels. It is a regular Rosemary's Baby of a code 'new arrival'."
