Experimental Investigation of Light-Gauge Steel Plate Shear Walls for the Seismic Retrofit of Buildings
MetadataShow full item record
This report presents experimental investigations into the seismic adequacy of steel plate shear walls (SPSW) utilizing light-gauge cold-rolled infill plates as a more viable option for retrofit scenarios. The interest in this type of system is that it would allow for an easily-installed retrofit, while being minimally disruptive to the functions in an existing building - especially in the context of hospital structures where modular systems for the rearrangement of floor plans are highly desirable. The report describes the prototype and specimen designs, experimental set-up, and results of three light-gauge SPSW concepts. Additionally, the report proposes a design procedure for SPSW based on the application of plastic analysis to an accepted analytical model for the representation of SPSW.
