On the Bidirectional Decoupling Characteristics of Toroidal Tuned Liquid Column Dampers

The current theoretical model of toroidal-tuned liquid column dampers (TTLCDs) is developed only for unidirectional excitation. For the bidirectional design, it is necessary to verify whether the liquid responses can be effectively decoupled in two principal directions. This article analyzes the dynamic response of TTLCDs under unidirectional and bidirectional excitation scenarios. The results reveal that the liquid responses of TTLCDs excited unidirectionally provide a good prediction for those excited bidirectionally, and the bidirectional response of TTLCDs can be simplified as the linear superposition of the response in two principal directions.
