摘要针对装设有设备大偏心高层工业厂房振动控制研究存在不足的问题，以醋酸厂钢结构厂房为研究对象，在理论分析和数值计算的基础上进行振动台试验。选取1:8的缩尺比设计制作了振动台试验缩尺模型。通过振动台试验测试了结构体系的动力特性，分别对无控制结构、设备上装设粘滞阻尼器的结构、同时在设备上装设粘滞阻尼器和在钢框架结构上装设磁流变弹性体阻尼器的结构这三种工况进行了无控制、被动控制和混合控制振动台试验。试验结果表明：在设备四周装设的粘滞阻尼器对设备减震效果显著，但对钢框架结构的减震效果很小；同时装设了粘滞阻尼器和磁流变弹性体阻尼器的混合结构控制策略对钢框架结构和设备的振动都有显著控制作用。

Abstract：

The problems existing in big eccentric high-rise industrial workshop with equipment vibration control have been studied, and acetated steel plant as the object of study, theoretical analysis and numerical calculation of vibration table test.Selected 1∶8 scale shaking table test of scale model was designed and fabricated.By the shaking table test of dynamic characteristics of structural system, no control structure, installation of viscous damper device structure, installation of viscous damping on both the device and the steel frame structure installed magnetorheological elastomer damper on the three conditions of no control, passive and hybrid shaking table test, were measured respectively.Test results show that the viscous damper installed around devices has big damping effect on equipment, but the effect on steel frame is very small.Also, the strategy equipped with viscous damper and magnetorheological elastomer damper has significant control on steel frames and vibration equipment.

Key words： High-rise industrial building Vibration control Viscous damper Magnetorheological elastomer damper vibration table test
