Composite Plate Shear Walls--Concrete Filled (C-PSW/CF) [N71B]Composite plate shear walls--concrete filled (C-PSW/CF)--are an alternative to reinforced concrete walls especially when relatively large seismic demand on the walls leads to dense reinforcement and large thicknesses in conventional concrete shear walls, or to relatively large walls thicknesses of the web infill and boundary elements in SPSW. New design provisions have been introduced in Section H7 of the AISC 341-16 Seismic Provisions, allowing the design of C-PSW/CF with or without boundary elements to address high seismic demands. This session will provide an overview of the new design requirements in that Section H7 and of the research that supports those requirements, followed by a description of a 59-story building in Seattle designed with a central core of concrete-filled composite plate shear walls (and supplemented by mid-height outriggers and belt trusses to enhance the overall stability and stiffness of the tower).
