The construction of concrete water tanks is a crucial aspect of water distribution structures, ensuring dependable water supply at predetermined elevations for numerous purposes. Municipalities and corporations closely depend upon these tanks to store water, combustible fluids, and synthetic compounds. However, the safety of these tanks, especially during seismic events, is paramount. To address this, robust support structures inclusive of reinforced concrete (RC) propped outlines, metallic frameworks, RC shafts, and masonry platforms are employed. The RC casing approach could be the most common support system due to its effectiveness and durability. This paper gives a FEM based technique the use of Staad.pro employed inside the construction and evaluation of concrete water tanks.
