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
