Investigation of Seismic Behavior of Coupled Steel Shear Wall Designed with Performance-Based Plastic Design Method

Abstract

Coupled steel plate shear wall consist of two shear wall with flat web plate with rigid beam-column connection, that connected with coupling beam at story level. Coupled steel plate shear wall consist of two panels with rigid beam-column connection, that connected with coupling beam at story level so its possible to use opening in wall. In this study, two types of six story steel plate shear wall with coupling beam with trapezoidally corrugated infill plate designed with performance plastic design method and two other types designed with force base design. All models have been designed in ABAQUS software and the software outputs were compared and verified by the behavioral mechanism of uncoupling shear wall of the trapezoidal corrugated sheet and the shear wall of the flat web sheet. Subsequently, these four samples were analuzed with time history analysis with the three Northridge, Kobe and Tabas earthquake records. Investigated output of this study consist of relative drift at the peak of maximum displacement of each records and residual drift. With the result of these four models figure out that relative drift are in allowable drift ratio (2%). But each design procedure has advantages than the other one. Advantages of performance plastic design in comparison with force base design are consume less steel material and distribute uniform relative drift ratio. While the advantages of force base design has less relative drift ratio. Hence, in frames which designed by force-based design in comparison with performance based plastic design has less residual drift.
