Final answer:
A torque link damper is used to reduce oscillations in structures like tall buildings. It consists of a reservoir of water that oscillates at the same frequency as the building's natural frequency, helping to stabilize the structure.
Step-by-step explanation:
The function of a torque link damper is to reduce oscillations in structures, such as tall buildings, caused by seismic activity and fluctuating winds. It is a tuned-mass damper that consists of a reservoir of water located at the top of the building. The water in the damper oscillates at the same frequency as the building's natural frequency, helping to dampen oscillations and stabilize the structure.
