Developing self-centering coupled shear walls for Seismic resilient tall buildings
FY 2023-24
Summary
Coupled walls are common lateral force-resisting systems in tall buildings. Recently, a new steel composite shear wall system has been proposed and used for high-rise construction. These modular core systems offer several advantages, including reduced construction schedule, rapid erection, increased strength, stability, and blast resistance, and more accurate tolerances in steel erection compared to traditional reinforced concrete shear walls. Despite these benefits, steel composite walls with coupling beams experience damage in severe earthquakes. The damage spread along the entire building height causes financial losses associated with post-earthquake repair and business disruption. The proposed research will develop self-centering walls to protect mid- and high-rise building structures from earthquake damage. Through collaborations with industry partners from the Canadian Institute of Steel Construction and Thornton Tomasetti, this research will enhance the seismic resilience of tall building structures in Canada.
