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。
In order to study the damping effect of mixed structure control of viscous damper and MR damper on large eccentric high-rise steel structure chemical plant, 12 viscous dampers are installed around the equipment, and 12 magnetorheological elastomers The damper is installed in the steel frame structure in the form of interlayer support. The single control structure of the non-controlled structure and the viscous damper and the mixed control structure of the viscous damper and the magneto-rheological elastomer damper are respectively subjected to the octave Eicentro wave, TAFT wave, shaker test with artificial wave (peak value: 400 cm / s2). Through the comparison of the structure response, the results show that the single damping viscous damper has a good damping effect on the equipment and the damping effect on the steel frame structure is very small. However, The devices all play a very good controlling role, and the hybrid control of both dampers is superior to a single damper control.
