What is BRB?
BRB stands for Buckling-Restrained Braces, which are steel braces designed to act as hysteretic dampers for dissipating seismic energy. They can be used in both existing and newly constructed structures, including steel, reinforced concrete, and prefabricated buildings, particularly in regions with high seismic activity.
Advantages Compared to Existing Systems
Local and Cost-Effective
Lightweight
High Performance
Fast
Durable
Easy to Maintain
Retrofitting with Koparan BRB
Retrofitting made with Koparan BRB allow buildings to maintain their functionality during the process and remain operational immediately after an earthquake. This ensures that critical structures essential for daily life become safer under seismic effects and continue to meet the community’s urgent needs.

Deficiencies and Common Flaws in Existing Structures
Insufficient Lateral Stiffness and/or Strength
Vertical and Horizontal Irregularities (Torsion, soft story, weak story irregularities)
Insufficient Ductility
Weak Column-Strong Beam Configuration
Low Material and Workmanship Quality
Conventional Strengthening Techniques
Jacketing and Shear Wall Addition
Disadvantages
Structures Becoming Non-Operational
Structures like schools and factories become non-operational during the strengthening process.
Housing Crisis
Residents of residential buildings need to be evacuated.
Increased Seismic Load
Significant mass is added to the existing system.
Challenges in Integration
Difficulties arise in ensuring the newly added elements work seamlessly with the existing system.
Internal Strengthening
External Strengthening
