Abstract

A building with TLD to earthquake Y-H. Chen', W-S. Hwang^ & C-H. Ko' * Department of Civil Engineering, National Taiwan University, Taiwan ^Department of Naval Architecture and Ocean Engineering, National Taiwan University, Taiwan Abstract The dynamic analysis of a building with Tuned Liquid Damper (or TLD) subjected to ground motion are presented. The water sloshing of TLD and the vibrational reduction of the building are highly emphasized and intensively studied. The time-step space-state vector is applied to calculate the transient response of the building, and in the same time step, the boundary element method with the second-order Taylor series expansion and Lagrangian description is utilized to solve the non-linear water-sloshing problem. The present work has been successfully employed for the calculation of the free surface movement of TLD and the dynamic response of the building to a recorded earthquake, such as the Chi-Chi earthquake (Taiwan, 1999).
