Seismic response of the passive controlled structure using buckling-restrained braces (BRB) can be ensured when the BRB connection have sufficient strength. Therefore, it is necessary to prevent the occurrence of slippage or yielding at the connections. In this paper, parametric seismic response analysis was conducted to clarify main factors concerning strength of connections that will affect seismic response of structures. In the analysis, strength variations of BRB and bolted connection are considered. Finally, in order to ensure performance of passive controlled structures and decrease damage of frames, the methodology to determine the demand of strength for connections is revealed.
