摘要: 為研究黏滯阻尼器對(duì)裝配整體式框架結(jié)構(gòu)抗震性能的影響,分別設(shè)計(jì)制作了 1 榀帶黏滯阻尼器的裝配整體式鋼筋混凝土框架模型和普通裝配整體式鋼筋混凝土框架模型。 對(duì)兩模型進(jìn)行了水平正弦激勵(lì)荷載作用下的抗震性能試驗(yàn),研究了兩模型的滯回特性、耗能能力等。 試驗(yàn)結(jié)果表明:設(shè)置黏滯阻尼器框架的滯回曲線較普通框架飽滿,結(jié)構(gòu)的耗能能力及附加阻尼比顯著提高,結(jié)構(gòu)的抗剪剛度增加,地震響應(yīng)顯著減??;設(shè)置黏滯阻尼器框架結(jié)構(gòu)的滯回特性與加載位移相關(guān),加載頻率變化對(duì)兩模型的滯回特性影響較小。

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.
