Viscous Damping Wall

Viscous damping wall

The viscous damping wall is a new type of energy-dissipating and shock-absorbing component for building structures. It is mainly installed in high-rise buildings in areas prone to disasters such as earthquakes and typhoons. When relative displacements occur between the upper and lower floors of a building during a typhoon or an earthquake, the viscous damping wall can convert the kinetic energy generated by the building into heat energy, thus achieving the purpose of energy dissipation and shock absorption. Since the viscous damping wall is a velocity-dependent damper without stiffness, it will not change the inherent dynamic characteristics of the structure during operation. It only provides additional damping for the structure. The damping force-displacement hysteresis curve is full and resembles a rectangle, endowing it with stable dynamic characteristics and a strong energy dissipation capacity.

Coupling Beam Dampers

The damping medium basically does not come into contact with air, and the filling material is not easy to age. Its performance hardly changes during normal use, and no maintenance is required. The viscous damping wall is a velocity-dependent damper. As the velocity increases, its damping force increases. It is effective for both small and large displacements, has good cyclic performance, and good resetability after an earthquake. It can effectively reduce the acceleration response of the upper structure and is effective for both wind vibration and earthquake action, being able to simultaneously meet the comfort requirements of wind loads on high-rises and seismic requirements. We can freely design the parameters of the damping wall based on the building scale and shock absorption requirements. It is not only suitable for the shock absorption design of new buildings but also can be used for seismic reinforcement and post-earthquake repair of buildings.
