This study examines the structural performance of different Elevated Storage Reservoirs (ESRs) under static earthquake conditions, focusing on Zone V, a severe earthquake zone, to provide water for human habitation and industry. The study analyses axial forces, bending moments, staging displacement, and horizontal bending moments in columns, beams, and tank walls, revealing significant structural variations among different shapes. This comparative analysis enhances ESR design philosophy for economical, safer, and cost-effective solutions, enhancing resilience in earthquake-prone areas for essential water supply.
