Passive mass dampers are used for wind, not earthquakes. their performance for earthquake is so bad that researchers don't even bother studying it.

If you use google scholars, the only results you get are researchers mentioning in their intro that passive systems don't work for seismic and then they propose an active (ei. with motors, pumps, etc.) system or a semi-active system (ef. fluid dampers with electronically controlled valves).

Passive mass dampers (ei. no valves, motors, etc.) like the one in Taipei 101 require too long to resonate with the earthquake and dissipate energy. by the time they start doing work, the earthquake is over.

This subject is like airplane lift explanations, the misinformation gets repeated so much that it even make its way into college textbooks.
