水平地震作用下巨-子型有控结构的动力响应研究

针对巨一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一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,且能改善巨一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.

Study on dynamic responses of mega-sub controlled structure under horizontal seismic

To avoid the collision between the mega-frame and sub-frame 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...
