چکیده:

Steel plate shear walls (SPSW) consist of thin web steel plates that infill frames of steel beams and columns, denoted as horizontal and vertical boundary elements, respectively. The unstiffened thin web plates have a tendency to buckle at small lateral loads and the so-called tension field develops, providing ductility and energy dissipation through tension yielding of web plate. In this paper, the over-strength, ductility, and response modification factors of code-based designed SPSWs is assessed by performing static pushover analysis, nonlinear incremental dynamic analysis as well as the linear dynamic analysis of model structures with various stories. According to the analysis results, the response modification factors derived from nonlinear incremental dynamic analysis match well with values given in design codes. It was also found that the number of stories of buildings has great effect on response modification factors, especially those obtained from static pushover analysis.
