چکیده:

AISC-341 provides requirements for designing of SPSWs by means of a capacity-design method in which boundary elements are designed for forces corresponding to the fullyyield strength of the web plate. This paper investigates the potentialities of the pushover analysis to estimate the seismic deformation demands of steel plate shear wall (SPSW).Reliability of the pushover analysis has been verified by conducting nonlinear dynamic analysis on 9,6 & 3 story frames subjected to STRONG MOTION RECORDS FROM THE 2011 OFF THE PACIFIC COAST OF TOHOKU EARTHQUAKE . The analysisutilizes a finite element method involving both material and geometric nonlinearities. It is shown that pushover analysis with predetermined lateral load pattern provides questionable estimates of interstory drift, lateral displacement and base shear
