摘要:: 目前 , 带裙房高层建筑层出不穷 , 底盘大的高层建筑可以使用于人口密集区 , 符合人类生活需求。而带裙房高层建筑也可理解为竖向收进建筑 , 结构竖向收进将存在刚度异常 , 抗震性较差等弊端。为此 , 提出基于调质阻尼器的带裙房高层建筑地震反应半主动控制方法。先构建 ER/MR 智能杆件的力学模型 , 分析 ER/MR 智能杆件的力学特征 , 之后通过 ER/MR 智能阻尼器的 “ 开关 - 耗能 ” 半主动控制策略 , 实现基于调质阻尼器的带裙房高层建筑地震反应半主动控制。实验结果表示：该方法控制下 ,ER/MR 智能杆件径向设定时 , 减震效果较佳；该方法减震性、实时性、可靠性、可操作性、合理性以及有效性的满意率均大于 0.97。

Abstract:: At present,high-rise buildings with podiums emerge in endlessly,and high-rise buildings with large chassis can be used in densely populated areas,meeting the needs of human life. The high-rise building with podium can also be regarded as the vertical building,which will have some disadvantages such as abnormal stiffness and poor seismic resistance. Therefore,the semi-active control method of seismic response of highrise building with podium based on the tuned mass damper is proposed. Firstly,the mechanical model of ER/ MR intelligent members is constructed,and the mechanical characteristics of ER / MR intelligent members are analyzed. Then,through the semi-active control strategy of "switch energy consumption" of ER / MR intelligent dampers,the semi-active control of seismic response of high-rise buildings with podium buildings based on the damper is realized. The results show that under the control of this method,the damping effect is better when ER / MR intelligent members are set radially,and the satisfactory rate of damping,real-time,reliability,operability,rat ionality and effectiveness of this method is greater than 0.97.
