TLD Introduction
A passive control device using one or more specially designed containers partially filled with liquid, usually water. The sloshing frequency is tuned to the main structural frequency.
TLD Introduction 2
When the structure vibrates under wind or other loads, liquid inside the TLD resonates. Liquid sloshing, wave breaking, and wall friction absorb and dissipate structural vibration energy.
TLD Introduction 3
The principle can be summarized as opposite-phase resonance and energy dissipation, helping tall flexible structures remain stable under strong wind.
