摘要
提出了袋式除尘器在水平地震作用下的计算模型,建立了结构的运动微分方程,分析了其抗震性能,得出了悬挂布袋对除尘器主体结构有良好的减震效果的结论。并对结构在3种不同地震波作用下进行了时程分析,发现场地土类别和地震波的特性对其减震率有一定的影响。
The structure of Dust Catcher with Sack is a favorable kind of aseismatic structure .An analytical model of Dust Catcher with Sack in the influence of horizontal earthquake is proposed, the differential coefficient equation of the fi＇amework is theorized and the aseismatic performance of the structure is analysised in this article,conclusion come that the suspended sacks bring excellent aseismatic effect to the structure .Time-History analysis under three different seismic waves is processed.It is found that the kind of the ground and the characteristicness of the seismic waves has an influence on the ratio of damping to some extent.
