中文摘要：

针对高层结构在地震作用下层间位移较小,阻尼器性能无法充分发挥的特点,提出一种用于油阻尼器的位移放大装置,可使油阻尼器两端的相对位移放大,提高其产生的阻尼力和耗能能力。以某实际工程结构为背景,基于SAP2000建立其多质点有限元模型,分析两种减震方案在3条地震波作用下的最大层间位移角、基底剪力、加速度放大系数、滞回曲线、能量耗散曲线,以检验位移放大型油阻尼器对结构地震响应的减震效应。结果表明,位移放大型油阻尼器能以更少的布置数量满足减震设计要求,同时获得较普通油阻尼器更为理想的减震效果。

英文摘要：

For high-rise structures, the drift ratiounder earthquakesis small so thatdamper performance cant be fully played. Aiming at thischaracteristic, a kind of displacement amplification device for oil damper was presented. The relative displacementat both ends of oil damper can be amplified, and it＇s damping force and energy dissipation ca- pacity can be improved. For test thevibrationreduction efficiency of seismic responseofdisplacement amplification oil damper, five structure indexes such as maximum of thedrift ratio, base shear, acceleration amplification coefficient, hysteresis curve, energy dissipation curveof two kinds of schemeunder threeseismie waveswere analysed, through a practical engineering structure. The multi-particlefinite element model were establishedbased on SAP2000 program. It is conclude that the displacement amplification oil damper canmeets design requirements with fewer layoutand get more excellent damping effect than common oil damper.
