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。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.
