Abstract

Active tuned liquid column damper (ATLCD) develops from tuned liquid column damper (TLCD), adjusting the pressure in the gas chamber at the end of the liquid column using a pressurized reservoir. The design of the ATLCD should be based on the passive TLCD, the Q and S matrix is obtained on genetic algorithm. The control performance of active TLCD used in multiple degrees of freedom system was verified by a five-story structure subjected to earthquake excitation. This result indicates that the ATLCD installed at the high-rise building can achieve significant response reduction in comparison with that obtained by using passive TLCD.

Key words
