“…Inoue et al [11] studied the overall behavior of the panel BRB and the effectiveness of the proposed reinforcement at the ends of panel by test, but the lower edge of panel was fixed on the bottom beam, therefore, the clearance between the panel and the core brace across the width of the brace was made slightly larger in order to avoid the core brace impacting the panel under large story drift. However, Tokinoya et al [12] pointed out the core plate brace would buckle about its strong axis when the in-plane clearance was large, and besides, Kishiki et al [13] and Koetaka et al [2] found out the unbonded material and the clearance across the thickness of the brace had considerable influences on local and even global bearing capacity of the BRB, which provides helpful information for improving the seismic behavior of the panel BRB. The results of the experimental investigation by literature [14] show that the panel BRBs with reasonable configurations possessed desirable performance, and steel frames installed with those panel BRBs also exhibited good performance with better ductility and energy dissipation capacity.…”
