Several analytical and experimental investigations have been conducted
on steel plate shear walls in Canada, the United States and Japan, fo
llowing interest from the consulting and fabrication industries for th
eir incorporation as viable lateral load resisting elements in new or
retrofit construction. While numerous buildings with a vertically orie
nted steel plate for sheer strength have been constructed in each of t
hese countries, the lack of codified rules resulted in overly conserva
tive designs. Furthermore, the limit of analysis tools to the linear e
lastic range prevented utilization of the post-buckling strength of th
in, unstiffened steel plate webs bounded by a beam and column framing
system. A team of researchers from Canadian universities, consultants
and the steel industry undertook to provide succinct design guidelines
for the acceptance of the system by the general design profession. Cy
clic quasi-static and dynamic shake-table tests on large scale and sma
ll scale, single bay, multi-storey shear cores were conducted to exami
ne the system's ductility performance and to verify analytical models.
Further to this, a parallel design exercise of several buildings was
performed to evaluate the implementation of the proposed guidelines. I
n this study, three variations of a steel framed office building were
used as case studies. The examples differ primarily in the systems' re
quired ductility ratings. Competitive reinforced concrete designs were
also performed for economic comparisons. The details and current find
ings of this feasibility program are presented in this paper. (C) 1998
