［摘要］超高層結(jié)構(gòu)過大的頂點(diǎn)風(fēng)振加速度會(huì)令人感到不適和恐慌，使用液體黏滯阻尼器可增加結(jié)構(gòu)阻尼比，從而減小結(jié)構(gòu)頂點(diǎn)風(fēng)振加速度達(dá)到抗風(fēng)減振的目的。對(duì)抗風(fēng)振設(shè)計(jì)中液體黏滯阻尼器應(yīng)用中的有關(guān)問題進(jìn)行討論，包括液體黏滯阻尼器不同布置方式的減振率對(duì)比，阻尼器非線性模型的計(jì)算模擬方法，液體黏滯阻尼器的型號(hào)選取、安裝、維護(hù)等。同時(shí)通過工程案例，說明合理布置液體黏滯阻尼器可以有效地減小超高層結(jié)構(gòu)頂點(diǎn)風(fēng)振加速度，提高其風(fēng)振舒適度。

Abstract:Excessive apex wind vibration acceleration of super high-rise structures can cause discomfort and panic. Using liquid viscous dampers can increase the structural damping ratio, thereby reducing the apex wind vibration acceleration of the structure to achieve the purpose of wind vibration reduction. Related issues in the application of liquid viscous dampers in wind-induced vibration reduction design were discussed, including the comparison of the vibration reduction rates about different arrangements of liquid viscous dampers, the calculation and simulation methods of the damper nonlinear models, and model selection, installation and maintenance of the liquid viscous damping. At the same time, the engineering case shows that the reasonable arrangement of the liquid viscous damper can effectively reduce the apex wind vibration acceleration of super high-rise structure and improve its wind vibration comfort.

Keywords:liquid viscous damper; super high-rise structure; wind vibration acceleration
