Numerical Study about Damping Effect of Liquid Damper on Tall Buildings

Abstract:

Based on the finite element method, three models are built: classical solid model, potential flow model and a combination of fluid-structure coupling model. Based on the above model the damping mechanism of tuned liquid damper has been investigated. Study focused on classical solid model and the boundary constrained potential fluid model respectively. After the completion of the above calculation, the analysis of bidirectional fluid-structure interaction model being carried out with the implicit dynamics algorithm. The results shows the contrast of the dynamic response of structure in the hydrated and anhydrous state. The calculations show that: the additional water mass can effectively reduce the natural vibration frequency of the structure, and it also can effectively reduce the displacement and velocity response of structure under vibration loads.
