Seismic Performance of Steel Multi-tiered Buckling-Restrained Braced Frames in Canada
This paper examines the seismic response of steel Multi-Tiered Buckling-Restrained Braced Frames (MT-BRBFs). A two-tiered BRBF part of a tall single-story building is designed per the current Canadian steel design standard seismic provisions. A nonlinear numerical model of the frame is developed, followed by nonlinear static and dynamic analyses to assess its global and local response, including tier drifts, Buckling-Restrained Brace (BRB) forces, and column demands. The results obtained from the analyses indicate that the non-uniform drift response due to the difference between the BRB’s strength in compression and tension imposes in-plane bending demands on the columns, which in combination with axial compression forces could result in column instability and should be considered in the design of the MT-BRBF columns.
