Seismic Analysis and Design of Elevated Circular Water Tank for Variation of H/D Ratio and Bracing Patterns

Abstract: Seismic analysis and design of elevated circular water tanks play a crucial role in ensuring the structural integrity and safety of these essential infrastructure components. This study focuses on investigating the effects of varying the height-todiameter (H/D) ratio and different bracing patterns on the seismic performance of such tanks. The analysis procedure includes a comprehensive numerical investigation using finite element analysis (FEA) software. The elevated circular water tank models are subjected to various seismic loading conditions to evaluate their dynamic response. Different H/D ratios are considered to assess their influence on the tank's behavior under seismic excitation. Additionally, the study explores the impact of different bracing patterns on the tank's seismic resistance. Various bracing configurations, such as radial, circumferential, and combined patterns, are investigated to identify the most effective design approach for mitigating seismic forces.
