Comprehensive Seismic Evaluation of Underground Water Tanks with Focus on Fill Conditions: An In-Depth STAAD.Pro Analysis

Abstract

The seismic analysis of underground water tanks is crucial for ensuring their structural
integrity and performance during seismic events. This review paper focuses on the seismic
analysis of underground water tanks considering different fill conditions, utilizing the
STAAD.Pro software for analysis purposes. The significance of seismic analysis in underground
water tanks and highlights the importance of considering fill conditions during the analysis.
Various fill conditions, such as empty, partially filled, and fully filled tanks, are investigated to
understand their impact on the structural behavior of the tanks. The paper reviews and
synthesizes existing literature on seismic analysis methodologies applied to underground water
tanks. It covers analytical and numerical approaches employed in previous studies, including
response spectrum analysis and time history analysis, to evaluate the seismic response of these
structures. Moreover, the abstract presents the key factors influencing the seismic behavior of
underground water tanks, such as tank geometry, soil-structure interaction, and seismic loading
characteristics. The effects of different types of backfill materials and their compaction levels on
the tank's seismic performance are also discussed. The review paper presents the findings and
observations from various studies, providing insights into the behavior and performance of
underground water tanks under different seismic conditions. These insights contribute to
improving the design and retrofitting strategies for underground water tanks, enhancing their
resilience to seismic activities. Overall, this review paper offers a comprehensive analysis of the
seismic behavior of underground water tanks considering fill conditions.
