This study examines the optimization of a movable floor system that functions as a dynamic absorber for the purpose of suppressing seismic motion in high-rise structures. Using the movable floor as an auxiliary mass to secure the mass, the optimal arrangement and parameters were designed focusing on the first-order and second-order natural frequencies of the high-rise structure. three evaluation indices, absolute floor acceleration, interlaminar deformation angle, and floor displacement, were used to validate the parameter values determined by the Genetic Algorithms (GA).
HASEGAWA et al. (Wed,) studied this question.
