Abstract:

Our previous study presented the vibration reduction efficiency of building models equipped with the V-shaped tuned liquid column damper (VTLCD) subjected to earthquake loads as a passive control problem. This study develops a hybrid control problem for VTLCD. The VTLCD is installed on the structure’s top floor, and the control force is placed on the structure’s first floor. The controller used to calculate this control force is based on the hedge-algebras (HA) theory, an advanced approach in automatic control. A U-shaped tuned liquid column damper (UTLCD) has also been included for comparison with VTLCD. The advantages of VTLCD over UTLCD were demonstrated in our previous research on the passive control problem and are further shown in this study on the hybrid control problem. Simulation results in this research show that the hybrid control configuration using VTLCD is significantly better at reducing structural vibrations than the one using UTLCD in all investigated earthquakes with different peak ground accelerations (PGAs). This efficiency increases as the PGA of the investigated earthquakes increases, demonstrating the advantage of VTLCD even in the case of hybrid control. This study has shown the potential of VTLCD as an effective solution to vibration control problems of structures.
