| Abstract: | Tuned liquid damper(TLD) and tuned liquid column damper(TLCD) are two types of passive control devices that are widely used in structural control. In this study, a real-time hybrid simulation(RTHS) technique is employed to investigate the difference in control performance between TLD and TLCD. A series of RTHSs is presented with the premise of the same liquid length, mass ratio, and structural parameters. Herein, TLD and TLCD are physically experimented, and controlled structures are numerically simulated. Then, parametric studies are performed to further evaluate the different performance between TLD and TLCD. Experimental results demonstrate that TLD is more effective than TLCD under different amplitude excitations. |
