Abstract: To date, the design of unstiffened steel shear walls has three issues that make them expensive to employ: 1) large columns resulting from the shear wall applying lateral loads to the columns; 2) expensive field-welded moment connections; 3) buckling of the steel plate under service earthquakes and winds. A new, innovative system, called the high-performance steel shear wall system, is developed and proposed by the authors to solve these problems. In this system: 1) the steel plate shear wall is not connected to the columns, therefore, the columns do not experience large lateral forces; 2) the beam-to-column connections consist of an innovative and cost-effective connection developed by the authors, referred to as a gusset plate moment connection; 3) the thickness of the plate is independent of the column size, enabling the use of thicker plates to prevent buckling of the steel plate under service loads.
