摘要:
为了验证旋转惯容阻尼器(RID)对巨-子结构体系在长周期地震动作用下的减震效果,基于强震动观测数据比较了近断层速度脉冲型地震动和远场类谐和地震动这两类长周期地震动的特点,通过建立RID-巨-子结构消能控制体系的振动微分方程,对比分析了两类长周期地震动对RID-巨-子结构消能控制体系和巨-子结构抗震体系地震响应的影响差异。结果表明,相对于巨-子结构抗震体系,RID-巨-子结构消能控制体系能有效减小结构体系在长周期地震动作用下的地震响应,减震效果明显。
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.
