［摘要］介紹了新型黏滯阻尼墻（VFW）的性能和減震原理，以及附加阻尼比的一種實(shí)用計(jì)算方法。分別計(jì)算了原結(jié)構(gòu)模型、設(shè)置VFW的消能器模型以及調(diào)整阻尼比的模型三者的地震響應(yīng)，通過(guò)對(duì)比設(shè)置VFW的模型與調(diào)整阻尼比的模型的計(jì)算結(jié)果，研究消能器為結(jié)構(gòu)提供的附加阻尼比。由分析可知，消能器耗能顯著，計(jì)算結(jié)果滿足減震目標(biāo)要求，消能減震設(shè)計(jì)方案能夠有效改善結(jié)構(gòu)性能，對(duì)控制結(jié)構(gòu)層間位移角、減小地震作用具有明顯作用。

Abstract:The performance and damping principle of a new type  viscous fluid damping wall (VFW) were introduced as well as a practical calculation method for the additional damping ratio. The seismic responses of three models were respectively calculated, including the original structure model, energy dissipation device model with VFW and the model with adjusted damping ratio. By comparing calculation results of the model with VFW and the model with adjusted damping ratio, additional damping ratio provided by energy dissipation device to the structure was researched. The analysis shows that energy dissipation device has significant energy dissipation effect, and the results meet the goals of damping. Energy dissipation design scheme can effectively improve the performance of the structure, and has an obvious effect on interlayer displacement angle control and reduction of the earthquake action.

Keywords:viscous fluid damping wall; energy dissipation design; damping ratio
