1. A stabilization system for a building, the stabilization system comprising:
a stabilization assembly configured to couple to a floor structure of a building, the stabilization assembly including:
a rotatable platform;
a track coupled to the rotatable platform, the track defining a track path;
a weight slidably coupled to the track; a tensile member engaging a drive wheel coupled to the weight;
at least tow actuators configured to
rotate the rotatable platform in a first direction and a second direction, and
move the weight along the track path in a third direction and a fourth direction;
at least one sensor configured to acquire measurement data relating to a seismic event; and
a controller configured to:
determine a target response of the stabilization assembly that mitigates an effect of the seismic event on the building based on the measurement data, and
control the at least two actuators to
rotate the rotatable platform in at least one of the first direction or the second direction, and
move the weight along the track path in at least one of the third direction or the fourth direction
 according to the target response.
