【摘要】：为研究粘滞阻尼器和磁流变弹性体阻尼器的混合结构控制对大偏心高层钢结构化工厂房的减震效果,将12个粘滞阻尼器安装在设备四周,12个磁流变弹性体阻尼器以层间支撑形式安装在钢框架结构中,分别对无控结构、粘滞阻尼器的单一控制结构以及粘滞阻尼器和磁流变弹性体阻尼器的混合控制结构进行八度罕遇Eicentro波、TAFT波、人工波(峰值为400 cm/s2)作用下的振动台试验。通过对结构响应的对比分析,结果表明:粘滞阻尼器的单一控制对设备的减震效果很好,对钢框架结构的减震效果很小;而两种阻尼器的混合控制对钢框架和设备都起到了很好的控制效果,并且两种阻尼器的混合控制优于单一阻尼器控制。
[Abstract]:In order to study the damping effect of viscous dampers and magnetorheological elastomer dampers, 12 viscous dampers were installed around the equipment, and 12 magnetorheological elastomer dampers were installed in the steel frame structure in the form of interlayer support, respectively, on the uncontrolled structure and viscous dampers, respectively. A control structure and a hybrid control structure of viscous dampers and magnetorheological elastomer dampers are used to carry out a shaking table test under the action of eight degrees Eicentro wave, TAFT wave and artificial wave (peak value of 400 cm/s2). By comparing the structural response, the results show that the single control of the viscous damper has a good shock absorption effect on the equipment. The damping effect of the frame structure is very small, and the mixed control of the two kinds of dampers has a good control effect on the steel frame and the equipment, and the mixed control of the two kinds of dampers is superior to the single damper control.
