Seismic Resistance and Parametric Study of Building under Control of Impulsive Semi-Active Mass Damper

When high-rise buildings are shaken due to external forces, the facilities of building can be damaged. A Tuned Mass Damper (TMD) resolve this issue, but seismic resistance TMD is exhausted detuning effect. The Impulsive Semi-Active (ISAMD) proposed with fast coupling and decoupling at active joint between mass structure overcome proof effects a ISAMD were compared. numerical analysis results indicate that: (1) reduction ratio maximum roof displacement response mean square root higher than 30% 60%, respectively; (2) sensitivity efficiency index frequency was very low, did not occur in ISAMD; (3) achieve stable ISAMD, its should 2 4; (4) amount control block reduced by enhancing stiffness auxiliary spring (5) has effect, regardless earthquake distance.
