How are mass dampers and active tendon systems similar in the way they protect a building from earthquake damage?

Mass dampers and active tendon systems both mitigate structural vibrations during earthquakes by absorbing and dissipating energy. Mass dampers use large weights to counteract oscillations, shifting to counterbalance motion, while active tendon systems employ cables that adjust tension in response to building movements. Both systems enhance a building's stability and reduce the risk of damage by minimizing the impact of seismic forces. Ultimately, they serve the same purpose of improving the resilience of structures against dynamic loads.
