摘要
结构物的储水装置常被设计成池式调谐质量阻尼器(池式TMD),液体的动力效应会影响调频阻尼系统的控制效果.结合调谐液体阻尼器(TLD)与TMD共同作用的原理,综合考虑池式TMD的总体控制效果,并提出运用最优动力方法对池式TMD进行设置.以结构物室内游泳池为例,研究不同池长设计值的池式TMD的控制性能.结果表明,运用最优动力方法设置的池式TMD的控制效果明显优于普通方法设置的池式TMD,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 are usually designed to be pool-type tuned mass dampers(pool-type TMD).Dynamic effect of sloshing water affects the performance of the whole tuned damper system.In view of this,the synthetical effect of both tuned liquid damper(TLD)and TMD are considered simultaneously,and the optimum dynamic method is proposed to set the pool-type TMD.An indoor swimming pool is taken as an example to investigate the control performance of pool-type TMD.Results show that the control effectiveness of pool-type TMD set by optimum dynamic method is much better than that set by general method,and the size design of the pool-type TMD set by the optimum dynamic method is more reasonable for the structural inner using space.
