Abstract

Based on both genetic optimizations in the frequency domain and time domain analysis, a thorough inquiry into optimum feedback factors of active tuned mass damper (ATMD) has been made in the present paper. We find out that the control effectiveness of the ATMD with the negative normalized acceleration feedback gain factors (NAFGFs) is better than that with positive NAFGFs in conditions of the reasonable parameters and approximately equal control forces via evaluating the effectiveness of the storey drift control, effectiveness of the floor absolute acceleration, strokes and peak control forces.

Key words

Vibration control / Earthquakes / Active tuned mass damper / Frequency domain and time domain analysis / Negative normalized acceleration feedback gain factors
