ABSTRACT:

This paper aims to investigate the efficiency of energy absorption members incorporated in thin-walled steel bridge structures against major earthquakes. Energy absorption members concerned here is buckling-restrained brace (BRB), which dissipates earthquake-induced energy through metallic yielding through axial tension and compression. Dynamic nonlinear time-history analysis has been performed. It is found that such an energy absorption member is effective in mitigating earthquake hazard.
