【摘要】：扭转调谐液柱阻尼器(torsional tuned liquid column damper,TTLCD)是一种有效的扭转振动控制装置.本文对该阻尼器在偏心框架结构中的设计方法进行研究,针对不同的倾斜管道投影点和倾斜角,建立了三种形式的扭转调谐液柱阻尼器在地震作用下的运动方程和控制力方程,给出TTLCD参数优化的具体公式,其方法为对比扭转调谐液柱阻尼器-偏心结构和扭转调频质量阻尼器(torsional tuned mass damper,TTMD)-偏心结构,将两控制系统转化,利用Den Hartog或Ikeda给出的调频质量阻尼器(tuned liquid mass damper,TMD)参数优化公式来实现TTLCD参数优化,最后给出TTLCD的设计流程.通过对一个四层偏心框架结构进行模拟,验证了理论设计方法的合理性.
[Abstract]:Torsional tuned liquid column damper (torsional tuned liquid column dampert TTLCD) is an effective torsional vibration control device. In this paper, the design method of the damper in eccentric frame structure is studied. According to the different projection point and angle of inclined pipe, the motion equation and control force equation of torsional tuned fluid column damper under earthquake action are established. In this paper, the formula for optimizing the parameters of TTLCD is given. The method is to compare the torsional tuned liquid column damper-eccentricity structure and the torsional FM mass damper (torsional tuned mass damper-TTMD) -eccentricity structure, and transform the two control systems into two control systems. The parameter optimization formula of FM mass damper (tuned liquid mass damper TMD) presented by Den Hartog or Ikeda is used to realize the parameter optimization of TTLCD. Finally, the design flow of TTLCD is given. The rationality of the theoretical design method is verified by simulating a four-story eccentric frame structure.
