Innovative Composite Coupled Core Walls for High-Rise Construction [U5]

This session will focus on the latest and most promising innovation in steel structures; namely, the use of composite coupled core walls in lieu of conventional reinforced concrete coupled core walls in high-rise construction. Composite coupled core walls consist of composite plate shear walls -- concrete filled (CF-CPSW) coupled together using steel beams or composite filled tubes (CFTs). This session will showcase the new signature building (Rainier Square) being constructed in downtown Seattle using this innovative technology. The discussion will highlight various innovative solutions used to improve the design, fabrication, and constructability of this structure. Additionally, the session will present the findings from recent research and testing performed to evaluate the design and performance of CF-CPSWs. The focus will be on the cyclic lateral load-displacement behavior of CF-CPSWs, and the effects of axial load level and section detailing on the response including stiffness, strength, and deformation capacity.
