Enhancing Structural Performance of Water Tank Stands: A Finite Element-Based Approach and Real-World Fabrication Using ASTM A36

This study addresses the structural challenges associated with 1000-litre Sintex water tank stands, particularly the risks of deformation and failure in non-concrete roof structures.Finite Element Analysis (FEA) was used to evaluate two design configurations using identical L-section dimensions under various loading conditions.ASTM A36 mild steel was selected for its strength, affordability, and ease of availability.The results showed that the modified design (Design 2) demonstrated significantly lower deformation and stress levels compared to the conventional Sintex design, despite both using the same L-section sizes (40x40x6 mm, 50x50x6 mm, and 60x60x6 mm).Design 2, implemented as a real-world application model, offered enhanced structural stability and safety.The findings underscore the importance of optimized design and material selection in creating reliable, durable, and cost-effective support systems for rooftop water tanks.
