| Abstract: | In this paper, a 9-storey steel frame equipped with BRBs is analyzed using nonlinear dynamic time-history analysis in OpenSEES finite element software. The influence of rigidity ratio of BRB to frame on main seismic performance indicators of the structure is investigated. The reasonable range of rigidity ratio is recommended. The research results can provide accordance for the design of BRB frame structures. |
