Buckling Restrained Brace assembled from core axial member
and restraining concrete or hollow section maintains stable hysteretic characteristic and absorbs seismic force effectively, and reduces damages of main structural frame.
By adopting Buckling Restrained Brace, the main structural frame
can be kept intact or less-damaged even under extreme loading conditions.

Characteristics

Stable Seismic Energy Dissipation
– Buckling Restrained Braces provide consistent restoring force under cyclic loading and effectively
absorb seismic energy, minimizing structural damage and horizontal deformation.
Reduced Horizontal Vibration
– Seismic energy absorption by Buckling Restrained Braces suppresses lateral vibration during earthquakes.
Protection of Primary Structural Frame
– Less damage to the main frame after severe earthquakes due to the energy-dissipating function of Buckling Restrained Braces.

Applications

Almost 40 years since their first application, Buckling Restrained Braces are still actively researched and are expanding in applications for bridges, buildings, and industrial plants.
