working principle:

The main part of the damper is two weight objects weighing about 150 tons suspended by steel cables, suspended at 90 layers (395 meters). When a strong wind strikes, the device uses sensors to detect the size of the wind and the degree of shaking of the building, and controls the counterweight to move in the opposite direction via a computer via a spring or hydraulic device, thereby reducing the degree of shaking of the building.

It works like a person who is shaking a boat and moves the body in the opposite direction of the boat to balance. If a strong wind blows from the north, the weight is like a huge "pendulum" swinging north, so that the wind damper will produce a force opposite to the wind, thus mitigating the building's shaking and offsetting the strong wind against the building. influences.

After using this device, the acceleration of strong winds on the building can be reduced by about 40%, so that even in the case of strong winds, people in the building can hardly feel the shaking of the building.
