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。
The performance and damping principle of the new viscous damping wall (VFW) and a practical method of calculating the additional damping ratio are introduced. The seismic responses of the original structural model, the energy dissipater model with VFW and the damping ratio model were calculated respectively. By comparing the calculated results of the model of VFW and the model of adjusting the damping ratio, Additional damping ratio. From the analysis, it can be seen that the dissipator consumes significant energy and the calculation result meets the requirements of the shock absorption target. The design scheme of energy dissipation and damping can effectively improve the structural performance and has obvious effect on controlling the displacement angle of the structural layer and reducing the earthquake action.
