Steel Structures Research Update: Ring-Shaped Steel Plate Shear Walls for Improved Seismic Performance of Buildings

Recently completed work on the innovative ring-shaped steel plate shear wall (RS-SPSW) is highlighted. The research was led by Dr. Matthew Eatherton, Associate Professor at Virginia Tech and an AISC Milek Fellow. Featured here is the research conducted at Virginia Tech, with a brief discussion of the RS-SPSW concept and behavior; a summary of the large-scale experiments; and selected nonlinear response history analysis results comparing conventional SPSW and RS-SPSW prototype buildings.
