ABSTRACT
A series of quasi-static cyclic loading tests on unstiffened plate shear panels is
described, All the panels tested exhibited adequate ductility and stable S shaped
hysteresis loops, with the energy absorbed per cycle increasing with the
maximum amplitude of shear displacement. A theoretical model for
predicting the hysteretic characteristics is presented, which incorporates the
influences of shear buckling of the web plate and plastic yielding of the web
plate and surrounding frame. Theoretical predictions are compared and show
satisfactory agreement with the experimental results. The simplicity of the
theoretical model is such that it can be readily incorporated in nonlinear
dynamic analyses of steel plate shear walls.
