| 摘 要： | ATLCD由调频液柱阻尼器(Tuned Liquid Column Damper,TLCD)发展而来,在TLCD液柱端部连接气压控制箱,通过引入控制气压对结构实施主动控制。采用被动TLCD优化设计方法设计阻尼比及频率比,采用LQR算法确定ATLCD系统的主动控制力,并对LQR算法中权矩阵采用遗传算法进行优化。以一五层钢框架结构为例,顶层装ATLCD用LQR算法进行主动控制,加载El-Centro地震波进行时程响应分析,比较无控结构及被、主动控制结构的时程响应结果表明,采用ATLCD的减振效果明显优于采用被动装置。

| Abstract: | Active tuned liquid column damper (ATLCD) develops from tuned liquid column damper (TLCD), adjusting the pressure in the gas chamber at the end of the liquid column using a pressurized reservoir. The design of the ATLCD should be based on the passive TLCD, the Q and S matrix is obtained on genetic algorithm. The control performance of active TLCD used in multiple degrees of freedom system was verified by a five-story structure subjected to earthquake excitation. This result indicates that the ATLCD installed at the high-rise building can achieve significant response reduction in comparison with that obtained by using passive TLCD. |
