Abstract
A semi‐active tuned mass damper (TMD) is proposed to control wind induced vibrations in tall buildings. The semi‐active TMD uses a small amount of external power to modulate the damping. The net result is the equivalent of a passive TMD with hydraulically controlled time‐varying characteristics. Simulation studies show the proposed system is superior to conventional passively controlled and comparable to actively controlled systems.Keywords
