Dynamic analysis of 20 stories frame strucrure considering tuned liquid damper

Abstract

ABSTRACT

This paper analyses the reductional vibration of Tuned Liquid Damper with Floating Roof in 3D frame structures for harmonic loading. TLD and frame structure are simulated by ANSYS open code software, the structure and water in tower are discretized by solid elements considering the interaction. The system to hamornic loading is solved by finite element method and dynamic balance toanalyse the reductional vibration to dynamic responses of structures. The parameters are the level of water and frequency of loadings to natural frequency and dynamic responses of structures.

Key words: Tuned liquid damper, frame structure, finite element method, harmonic loadings.
