Abstract

To improve seismic reduction and self-centering performance of buckling restrained braces (BRBs) placed in a steel power plant structure, magnesium alloy is used to completely or partly replace steel as the core material of BRBs. First, steel power plant structure models with BRBs using different core material are established respectively. Then, seismic response of these models is analyzed and compared. Results show that for steel structures placed with BRBs, their story shear force, displacement, plastic strength and residual deformation are quite different than the original one with common steel braces. Both magnesium alloy and steel-magnesium hybrid BRBs show better performance than steel BRB in reducing story drift and residual deformation. Moreover, for magnesium alloy and steel-magnesium hybrid BRBs, their merit of self-centering ability and energy dissipation are worthy for future research.
