Abstract:
The devastating impact of earthquakes on infrastructure, particularly elevated water tanks, underscores the limitations of static analysis in structural engineering. These tanks, vulnerable due to their height and the concentration of mass at the top, demand a nuanced understanding of their dynamic behaviour, especially considering fluid-structure-soil interactions during seismic events. Failures in historical earthquakes have often been traced back to inadequate structural codes and poor design, highlighting the need for realistic seismic analysis. This study investigates the seismic performance of circular elevated water tanks using STAAD Pro for numerical modelling, focusing on the effects of soil types, water levels, and bracing configurations on seismic resilience. Through experimental design analysis, it reveals significant influences of soil compliance, water content, and bracing systems on key seismic indicators like base shear, displacement, and overturning moment. The research advocates for advanced seismic design strategies, incorporating these factors to enhance the earthquake readiness of water tanks.
