Abstract

This paper explores the structural design of RCC Intze water tanks through a comparative approach using two prominent international design standards: the Indian Standard (IS 3370) and the American Concrete Institute (ACI 350) code. Elevated water tanks, particularly those of the Intze type, are vital for ensuring a dependable water supply in both urban and rural settings. Their unique configuration, featuring a cylindrical body with a conical base, enhances load distribution and promotes material efficiency. In this study, STAAD.Pro software was employed to model the tank and perform structural analysis under various load conditions, including gravity, hydrostatic pressure, and wind forces. The findings reveal notable differences in reinforcement detailing and concrete usage between the two codes. Designs based on the ACI code demonstrated a slight reduction in steel requirements, indicating potential material savings. Overall, the study offers insights into how code selection can impact design outcomes, enabling engineers to make informed decisions based on cost, safety, and regional practices.
