Dynamic Response of Multi-tiered Buckling-Restrained Braced Frames in High Seismic Regions of Canada
This paper aims to examine the seismic response of multi-tiered buckling-restrained braced frames (MT-BRBFs) with a focus on two- and three-tiered frames using the nonlinear dynamic analysis method. The prototype frames are part of a single-storey building located in Victoria, British Columbia, and Canada. The frames are designed according to the current Canadian steel design standard and their performance is examined under scaled ground motion accelerations. The results of the numerical simulations indicate that appreciable in-plane moments are imposed on the MT-BRBF columns due to the non-uniform distribution of frame inelastic deformations caused by asymmetric BRB hardening in tension and compression. This moment demand in combination with high axial compression forces led to yielding of the columns and should be considered in the design of MT-BRBF columns.
