In a previous paper, by using the continuous medium technique, the present
authors showed that every plane panel, used to brace tall building structur
es acted upon by horizontal forces, is approximately equivalent Lo another
panel composed of a shear wall joined to a two-column frame by pinned horiz
ontal bars. In this paper, the three-dimensional association of such panels
is considered. A simple example structure shows the advantage of the formu
lation, wherein very few parameters are needed to describe the whole struct
ural behavior. Copyright (C) 2001 John Wiley & Sons, Ltd.
