Abstract-A nonlinear analysis of the dynamic response of thin steel plate shear walls, with fixed beam
to column connections, based on a finite difference solution of the governing differential equation of
motion, is presented. The hysteretic characteristics of steel plate shear walls, incorporated in the analysis,
include the influence of shear buckling and plastic yielding of the web plate and plastic yielding of the
surrounding frame. The results presented validate the analysis for elastic response and demonstrate the
effectiveness of the hysteretic characteristics in inhibiting resonance under periodic dynamic loading.
