Abstract –Water is one of the important elements in our
According to their shape, water tanks are also categorized:
life. As water is used in many different fields like distribution of drinking water, agriculture, industry, fire fighting etc. All these purpose needs various types of flow throughout the year according to the use. We need to store the water to maintain the flow of water. For this purpose we have to construct an elevated water tanks. INTZE water tank is one of the large structures to store the water and these types of structure are build for long term use. These types of structures need to resist the strong wind load and earthquake loads. In this project total of three models were prepared one model with empty water condition, second model with full water condition and third model with half water condition with presence of wind in different terrain category. In this project the parameters displacement, bending moment and shear force is checked. The maximum values obtained in the full tank condition. With regard to terrain categorization, various models have been used in the comparison.
1. Circular tanks 2. Rectangular tanks 3. Intze tanks 4. Circular tank with conical bottom 5. Spherical tanks

1. INTRODUCTION Water is essential for the survival of every type of animal in the planet. Intze type are frequently utilized as water reservoirs. The basic components of an Intze tank are a Top Dome (roof), a cylindrical wall, and a floor slab made up of a conical dome and a bottom spherical dome. Both the movement of the tank with regard to the water inside it and the movement of the tank with respect to the ground must be considered when analyzing the dynamic behavior of these tanks. The current design of high water tank support structures is extremely vulnerable to lateral stresses as it is constructed for wind forces.
Top dome: In general, we supply a 110 to 150 mm thick top dome with reinforcement throughout the latitudes and longitudes. The dome's rise is typically one-fifth of its length. Top ring beam: There is a meridional thrust applied to the top ring beam. The beam is made to accommodate hoop stress brought on by water load.
1.1 Water Tanks in General and Water Tank Types:
Cylindrical walls: The principal force acting on the wall is hoop tension, which is brought on by water pressure. So, the wall is built to accommodate hoop tension.
Water supply projects are crucial for the nation's social and industrial growth and have attracted a lot of interest in recent years across the globe. Depending on how much water is used, water tanks come in a variety of capacities. Based on where they are located, water tanks are divided into three types.:
Ring beam at the bottom: This ring beam was installed between the cylinder wall and the conical slab. The ring beam is employed to offset the horizontal component of the cylindrical wall's reaction to the conical wall. The bottom ring beam's purpose is to support the tension created by the hoop.
1. Water tanks buried underneath 2. The tank is sitting on the ground.
Conical slab: The slab is subjected to both meridional thrust and hoop tension. Fluid pressure is what causes the hoop
3. Water tanks that are elevated.
