［摘要］耗能減震技術(shù)通過在結(jié)構(gòu)物的某些部位設(shè)置耗能裝置，利用其局部變形提供附加阻尼，以消耗地震能量，減小主體結(jié)構(gòu)地震反應(yīng)，從而達(dá)到減震、控震的目的。北京汽車產(chǎn)業(yè)研發(fā)基地項(xiàng)目建筑造型較特殊，結(jié)構(gòu)的扭轉(zhuǎn)效應(yīng)比較大，為了減小結(jié)構(gòu)的地震響應(yīng),尤其是在罕遇地震下的響應(yīng)，在關(guān)鍵部位布置了若干黏滯流體阻尼器。采用MIDAS軟件對(duì)采用阻尼器后的耗能結(jié)構(gòu)與初始結(jié)構(gòu)進(jìn)行計(jì)算比較。結(jié)果顯示，黏滯流體阻尼器的采用有效控制了結(jié)構(gòu)在地震作用下的響應(yīng)。

Abstract:The aim of reducing and controlling the earthquake response of the main structure can be realized by the energy dissipation technology which can be implemented by the additional damping of energy dissipation devices. The architectural modeling of Beijing Auto R&D Center is special and the torsion effect of the structure is large. Then the viscous fluid dampers are fixed on the key regions in order to reduce the earthquake response especially the strong earthquake response of the structure. The analysis result obtained by MIDAS proves the good vibration resistance effect of viscous fluid damper.
Keywords:viscous fluid damper; energy dissipation; earthquake response
