Nonlinear dynamic analysis of steel plate shear walls including shear and bending deformations

Abstract A nonlinear analysis of the dynamic response of thin steel plate shear walls, based on a finite difference solution of the governing differential equations of motion, is presented. The equations of motion incorporate both shear and overall bending displacements of the shear wall. The hysteretic characteristics of the individual storeys, incorporated in the nonlinear 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.
