［摘要］設(shè)計了一種新型黏滯阻尼墻，并通過水平動力加載試驗(yàn)，研究新型黏滯阻尼墻在不同振動頻率和位移幅值下的阻尼力與位移關(guān)系，探討了新型黏滯阻尼墻的滯回特性，以及振動頻率、位移幅值、速度、循環(huán)特性等對其動力性能的影響。研究表明，新型黏滯阻尼墻耗能效果較好，其阻尼力與速度有關(guān)，而與頻率無相關(guān)性；地震作用下，其耐久性較好。

Abstract: A new type of viscous damping wall was designed and the dynamic performance experiments were conducted. Relationship of damping force and displacement of viscous damping wall was studied under different frequencies and displacements. The effects of hysteretic characteristics, frequency, displacement range, velocity and cyclic properties on dynamic performance were discussed. The experiment results show that the viscous damping wall has well energy dissipation ability, while its damping force relates to velocity instead of frequency. The durability of viscous damping wall is well under the earthquake.

Keywords: structure control; energy dissipation; viscous damping wall; dynamic performance
