چکیده:
In this paper, we evaluated seismic performance properties of steel plate shear wall (SPSW)
using Consecutive Modal Pushover Procedure (CMPP). This method is performed on 3, 6
and 9-story SPSW frames subjected to seven earthquake records which are scaled according
to ASCE/SEI 7-05 provisions. We conducted nonlinear time history analysis (THA) to verify
extracted outputs. The SPSW models indicate a relatively accurate estimation in nonlinear
story drift and story displacement response of pushover procedures compared to that of the
THA with respect to responses like shear story; while, in the high-rise model in specific, the
deformation parameters are more accurate through an increase in the height of the models.

ir Peer review under responsibility of UCT Journal of Research in Science, Engineering and Technology INTRODUCTION In recent years, many attentions have been paid on high spectrum performance by many digital radio system During recent decades, major developments are being made in earthquake engineering and analysing structures under seismic loads.
Lateral force distribution in consecutive modal pushover analyses is based on mode shapes obtained from Eigen-analysis of the linear elastic structure.
Conclusion In this paper, seismic performance properties of steel plate shear wall (SPSW) are assessed using Consecutive Modal Pushover Procedure (CMPP).
