Abstract
This thesis investigates the dynamic behaviour of elevated water tanks, with a particular focus on the effects of sloshing and their application as tuned liquid dampers (TLDs) using ABAQUS software. Elevated water tanks play a critical role in urban infrastructure, but their dynamic responses to seismic and wind loads present significant challenges, especially due to the complex fluid-structure interactions induced by sloshing. To address these challenges, this study employs the Coupled Eulerian-Lagrangian (CEL) method within ABAQUS, a powerful approach that accurately captures the interaction between the fluid and the tank structure without the need for frequent remeshing. The CEL method allows for a detailed simulation of the sloshing behaviour of the liquid inside the tank, providing a comprehensive understanding of how these movements affect the overall dynamic response of the structure. The research begins with a thorough literature review, establishing the importance of understanding fluid-structure interactions and the efficacy of TLDs in mitigating structural vibrations. A detailed computational model of the elevated water tank is created in ABAQUS, incorporating geometric and material properties. The model is subjected to dynamic loading scenario of seismic loads, to evaluate the tanks performance. Simulations are conducted both with and without the implementation of TLDs, allowing for a comparative analysis of their effectiveness. The results demonstrate that the inclusion of TLDs significantly reduces the vibrational amplitudes of the tank, enhancing its seismic resilience and overall stability. The study also highlights the critical role of sloshing effects in influencing the dynamic behaviour of the tank, with the CEL method proving instrumental in accurately capturing these interactions. The findings contribute to the broader field of structural engineering by demonstrating the effectiveness of advanced simulation techniques in addressing complex fluid-structure interaction problems.
