Tuned mass damper
After seismic waves make a structure vibrate, a tuned mass damper (or seismic damper) can decrease their damaging effect and improve the building's seismic performance.[1] Vehicles use small dampers and buildings use large ones. Some examples of dampers' design and implementation are presented in the images below:
