摘要: 为研究黏滞阻尼器对装配整体式框架结构抗震性能的影响，分别设计制作了 1 榀带黏滞阻尼器的装配整体式钢筋混凝土框架模型和普通装配整体式钢筋混凝土框架模型。 对两模型进行了水平正弦激励荷载作用下的抗震性能试验，研究了两模型的滞回特性、耗能能力等。 试验结果表明:设置黏滞阻尼器框架的滞回曲线较普通框架饱满，结构的耗能能力及附加阻尼比显著提高，结构的抗剪刚度增加，地震响应显著减小；设置黏滞阻尼器框架结构的滞回特性与加载位移相关，加载频率变化对两模型的滞回特性影响较小。

Abstract: In order to study the effect of viscous dampers on the seismic performance of precast concrete frame structures，a precast concrete frame model with viscous dampers and a general precast concrete frame model were designed andproduced respectively. The seismic performance test under the horizontal sinusoidal excitation load was carried out on thetwo models， and the hysteresis characteristics and energy dissipation capacity of the two models were studied. The resultsshow that the hysteresis curve of the frame with viscous dampers is fuller than that of the general frame， the energydissipation capacity and additional damping ratio of the structure are significantly improved， the shear stiffness of thestructure is increased， and the seismic response is significantly reduced. The hysteretic characteristics of the framestructure with viscous dampers are related to the loading displacement， and the change of the loading frequency has littleeffect on the hysteretic characteristics of the two models.
