| 摘 要： | 针对巨-子型有控结构存在的因子结构加速度过大及位移过大可能会造成主、子结构碰撞的问题，本文设置了一种实际的粘滞阻尼器，分析水平地震作用下其对巨-子型有控结构动力响应的控制效果，通过改变粘滞阻尼器的安装位置，进一步讨论了粘滞阻尼器安装位置对其控制效果的影响，研究表明：粘滞阻尼器的设置不会影响子结构的调频作用，且能改善巨-子型有控结构的控制效果，减小主结构位移、子结构加速度响应，其在结构中的安装位置对控制效果影响显著。

| Abstract: | To avoid the collision between the mega-frame and sub-flame which caused by too large acceleration and displacement of the sub-frame for the mega-sub controlled structure, some viscous dampers are set up to improve the mega-sub controlled structure. An analysis of time history dynamic responses of the mega-sub controlled structure under horizontal seismic is made. It was shown that setting viscous dampers won＇t affect the role of modulating frequency of the sub-frame, and it can improve the effectiveness of the mega-sub controlled structure, reduce the displacement of the mega-frame and acceleration response of the sub-frame. In addition, the installation site of the viscous dampers in the structure significantly affect the control effect. |
