摘要
结构物的储水装置可被设计成调谐液柱/质量阻尼器(TLCMD);液体的动力效应会影响调频阻尼系统的控制效果。结合调谐液柱阻尼器(TLCD)与调谐质量阻尼器(TMD)共同作用的原理综合考虑了TLCMD的总体控制效果,并提出运用最优动力方法对TLCMD进行设置。算例分析表明:运用最优动力方法设置的TLCMD的控制效果明显优于普通方法,并为适应结构物内部使用空间要求提供了更为宽松的条件。
Water storage devices with the water weight can be designed to be an adjustable liquid column/ mass damper （TLCMD）. Dynamic effect of sloshing water affects tile performance of the whole adjustable damper system. In this point of view, tile synthetic effect of both adjustable liquid column damper （TLCD） and adjustable mass damper （TMD） are considered simultaneously, and the optimum dynamic method is proposed to set the TLCMD. Numerical results show that the control effectiveness of TLCMD set by optimum dynamic method is much better than that by general method, and the design of water column length of TLCMD set by the optimum dynamic method is more reasonable for the structural inner using space.
