BEHAVIOR OF PERFORATED STEEL PLATE SHEAR WALLS AGAINST HORIZONTAL LOAD

Abstract

ii ABSTRACT This paper presents the results from nonlinear finite element analysis conducted by ABAQUS/CAE program to investigate the behavior of perforated steel plate shear walls (PSPSWs). Finite element monotonic pushover analyses were conducted on complete perforated SPSW models with various geometrical parameters. A brief introduction and literature review of the previous work in the field of steel plate shear wall and perforated steel plate shear wall are presented. For verification, Three FE models are conducted, two single-story perforated and solid models and one three-story solid model, to verify the experimental work results of the previous researchers and to understand the behavior of perforated steel plate shear wall (PSPSW). Good agreement in overall behavior between the test results and the analytical models results was observed. For parametric studies on single story, different parameters such as specimen’s height, infill plate thickness, columns stiffness, perforations diameter, angle of perforations, reduced beam section diameter, material grade of the infill plate, beams stiffness and perforations layout are considered. This research aims to study the effect of each parameter on the behavior of perforated steel plate shear walls to investigate which factor should be considered in the analytical calculations to predict well the strength of perforated steel plate shear wall (PSPSW). A modification to previous finding for the strength of PSPSW is proposed in relation with solid SPSW.
