Hysteretic behavior of a tandem self-centering double-stage yielding buckling-restrained brace

Key Points

• Hysteretic behavior enhances the energy absorption capacity of the brace, improving structural resilience.
• The double-stage yielding mechanism provides effective performance under different loading conditions.
• Assessment using experimental setups for evaluation of the self-centering brace’s behavior in seismic scenarios.
• Results suggest potential for enhanced safety in building designs with innovative brace technology.
