Abstract:

Due to colossal needs by the public, water has to be stored and supplied according to their requirements. Water demand is not constant throughout the day. It fluctuates from hour to hour. To supply a constant amount of water, we need to store water. To fulfill the water demand, water tanks need to be constructed. Water tanks are playing an important role in municipal water supply and firefighting systems. As Known from very upsetting experiences, elevated water tanks were heavily damaged or collapsed during the earthquake. This was might be due to the lack of knowledge regarding the proper behavior of the supporting system of the tank again dynamic effect and also due to improper geometrical selection of staging patterns. Without taking into consideration seismic load is one of the most critical facts for reducing seismic vulnerability. Therefore different configurations of liquid storage tanks have been constructed. This paper presents a time history analysis of intze elevated liquid storage tanks supported on RC framed structure with different capacities, different Staging configurations, and full and empty conditions on three different soil types (Hard rock, Medium soil, Soft soil). Tank responses including base shear, overturning moment, and roof displacement have been observed, and then the results have been compared. Results state that the dynamic analysis replies as base shear, overturning moment, and displacement are vastly influenced.
