Verification of Consecutive Modal Pushover Procedure for Estimating the Seismic Performances of Steel Plate Shear Walls

Abstract

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.

“…Te B31 is a 2-node beam element with linear interpolation formulations in three-dimensional space. Tis element allows for transverse shear deformation [28]. Te T3D2 is a two-node, 3-dimensional truss element used in two and three dimensions to model slender, line-like structures that support only axial loading along the element [29].…”
