Comparative Study of RCC Rectangular Underground Water Tanks Considering earth quake and without earth quake condition

Abstract

There are various kinds of water tanks and reservoirs that are used for storing different liquids such as water, petroleum, and chemicals. Residential and commercial use of water tanks is essential in order to meet the needs of those living in these places on a daily basis. During their lifetime, these tanks are subjected to the pressure of the water inside and the pressure of the earth outside. The tank bases are subjected to soil reaction from the bottom and internal water pressure from the inside. In order to protect them from top to bottom, they are always covered from top to bottom. Providing optimum height for easy pumping of water to the overhead tank is the purpose of this rectangular underground tank. Due to the underground nature of the water tank, lateral earth pressure and water pressure also need to be considered during design calculations, so the design must comply with IS code standards. An underground rectangular tank is designed in this project. Our project involves the design and research of an underground water tank capable of holding 3 lakh litters under earthquake conditions. The design in this project comprises of side walls, base slab and roof slab. STAD.PRO is used for the analysis and design of underground water tanks. For this design project limit state method is used. Researchers investigate parameters related to water tanks, including shear force and bending moment, to better understand how they respond to seismic forces, and to aid in more effective design and construction.
