Abstract

Tuned liquid column damper (TLCD) was developed mainly for the purpose of suppressing horizontal motion of structures. No relevant research has been found on the suppression of structural pitching vibration by using TLCD. This paper thus conducts a series of TLCD experiments with different configurations and parameters to investigate the possibility and effectiveness of applying TLCD to reduce pitching motion of structures. A theoretical model of TLCD-structure interaction under pitching motion is also developed to guide the experiments and verified by the experimental results on the other hand. In this study, the influences of variable TLCD parameters on control effectiveness are determined. It is concluded that TLCD can efficiently reduce structural pitching motion.
