- Abstract:
-
In order to verify the damping effect of the Rotation Inertia Damper(RID)on the mega-sub structure system subjected to long-period ground motions,the characteristics of two types of long-period ground motions named far-field harmonic-like ground motion,near-fault with,velocity pulse ground motions.are compared based on the statistical analysis of strong-motion data.The effect of these two types of ground motions on the RID-passive,mega-sub controlled system and the mega-sub,aseismic system are analyzed by establishing the vibration differential equation.The results show that on this occasion,the RID-passive,mega-sub controlled system is more capable of reducing seismic response than the mega-sub aseismic system.
