| Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 96 === In this thesis, the passive control theorem and the design parameters of Tuned Mass Dampers (TMD) and Tuned Liquid Dampers (TLD) will be introduced. Both methods are applied to TAIPEI 101 subjected to earthquake or wind loading as the case study and the efficiency of both dampers will be discussed.
In this study, a TLD with water inside a rigid tank interacts with a structure subjected to a horizontal excitation. The nonlinear sloshing is considered inside the tank based on the theory of potential flows. The Boundary Element Method with the Lagrangian coordinate description of the free surface and the Taylor series expansion of time are used to solve the transient velocity potential and its normal gradient on the free surface. The hydrodynamic pressure on the tank wall can be obtained by using Bernoulli’s Equation, and then the base shear force can be calculated from the hydrodynamic pressure on the tank wall. The base shear force will be counted to the structure at the next time step. Finally, the structure as well as the liquid transient responses can be resulted by turns.
