[摘要]介绍了新型黏滞阻尼墙(VFW)的性能和减震原理,以及附加阻尼比的一种实用计算方法。分别计算了原结构模型、设置VFW的消能器模型以及调整阻尼比的模型三者的地震响应,通过对比设置VFW的模型与调整阻尼比的模型的计算结果,研究消能器为结构提供的附加阻尼比。由分析可知,消能器耗能显著,计算结果满足减震目标要求,消能减震设计方案能够有效改善结构性能,对控制结构层间位移角、减小地震作用具有明显作用。

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
