Abstract

This paper presents results of the seismic capacity of buckling restrained braces (BRBs) with inter-story drift in steel single portal frame. Seismic capacities of BRBs were tested as an energy dissipation device under axial load in past studies. But, loading condition of the BRB installed at the frame, eccentric axial load acts on both ends of the BRB by the drift. Firstly, to optimize the seismic control design in steel portal frame with BRB, numerical analyses were studied. Secondly, to limit the length and the cross-sectional area of damping member of the BRB, design details were proposed. Finally, it was confirmed that the BRBs had good seismic capacities in the inter-story drift under eccentric axial load by hybrid test.
