Abstract :
Over the past decade of extensive research works, the thin un-stiffened steel plate shear wall(SPSW) has now emerged as a promising lateral load resisting system. Considering thedemand of performance-based seismic design (PBSD) philosophy in current and futureseismic design codes, a ductility-based design was recently proposed for SPSW systems withpin-connected boundary beams. However, the effectiveness of that method was not testedusing standard steel sections. The focus of this paper is to check the applicability of thatPBSD procedure for practical designs of SPSW systems in the US and Indian context, usingstandard rolled steel sections available commercially in these countries. Based on sampledesign case studies on 4-story test buildings, the method is found to be a practicable solutionfor PBSD of SPSW systems. In addition, the distribution of inter-story drift over the height ofthe structure is also found to be suitable for adopting in design guidelines. The need forwidening the range of available Indian Standard sections for realistic PBSD applications is
