tuned mass damper

A tuned mass damper is a device installed in buildings or structures to reduce vibrations caused by forces like wind or earthquakes. It consists of a large mass, such as a heavy weight, attached to a structure through springs or dampers. When the building starts to sway, the damper moves in opposition to the motion, absorbing some of the energy and minimizing motion. This helps protect the structure, improve stability, and make it more comfortable for occupants. The system is "tuned" to match the frequency of the building’s vibrations, ensuring maximum effectiveness.
