摘要 黏弹性多维隔减震装置是一种新发明的被动控制装置,具有隔震和减震性能。为掌握该装置在水平地震作用下对结构的隔减震效果,对加与未加装置的钢框架结构进行水平向振动台试验,对加与未加装置结构的动力特性、加速度反应和位移反应进行比较,并将模型结构的有限元分析结果与试验结果进行对比。试验和理论研究表明:该装置在水平方向上对结构既具有良好的隔震作用,又具有较好的减震效果,是一种有效的隔减震装置。 Viscoelastic multi-dimensional earthquake isolation and mitigation device is a new type of passive control device. In order to grasp the earthquake isolation and mitigation effect of the devices for structures, shaking table tests of steel frame structures with and without the devices are carried out. The dynamic characteristics, acceleration and displacement responses of structures are analyzed, and the finite element results are compared with the experimental data. The study indicates that such devices may isolate and mitigate the effects of earthquakes.
