CBD (Coupling-Beam Damper)

Left Side: The coupling beam directly connects two shear walls without any additional seismic energy dissipating elements

Right Side: Diagonal elements, shown in red, have been added inside the coupling beam. These elements function as seismic energy dissipators (CBD) or damping components. Such systems dissipate energy during an earthquake, enhancing the structure’s resilience.

This configuration controls the deformation of the coupling beam, ensuring more effective seismic performance during earthquakes. Commonly used in high-rise buildings and viaducts, these seismic energy dissipation systems increase the structure’s rigidity and energy absorption capacity, minimizing damage
