Experimental Investigation of Light-Gauge Steel Plate Shear Walls for the Seismic Retrofit of Buildings;Technical rept

摘要

Steel plate shear walls (SPSW), which are allowed to buckle in shear and form a diagonal tension field, have been used as lateral load resisting systems for buildings. Research, both analytical and experimental, shows that these systems can be ductile, stiff, and have stable hysteretic energy dissipation when hot-rolled infill plates are used. However, the demands imparted on the surrounding framing in a seismic retrofit situation are substantial, and in most cases, the existing framing is likely insufficient. SPSW utilizing light-gauge cold-rolled infill plates could be a more viable option for retrofit scenarios. The work presented here experimentally investigates the seismic adequacy of such a system. This report describes the prototype design, specimen design, experimental set-up, and experimental results of three light-gauge steel plate shear wall concepts. Additionally, a design procedure for SPSW based on the application of plastic analysis to an accepted analytical model for the representation of SPSW is proposed.
