ABSTRACT: The seismic performance demands of steel plate shear wall (SPSW) are estimated through
the conventional pushover procedures. Reliability of the pushover analysis is verified through nonlinear
time history analysis (NTHAs) on 9-, 6- and 3-story SPSW frames subjected to seven scaled earthquake
records according to ASCE/SEI 7-05 provisions. Story drifts, displacements and story shears are the main
parameters studied. A relatively accurate estimation is observed by pushover procedures compared to
NTHAs. The accuracy of estimation shows an increase with respect to the height.
Keywords: Steel plate shear wall; conventional pushover analysis; nonlinear time history analysis
