Design of Circular Water Tank by using STAAD Pro Software

Water tank are very useful for storage of water to occupy the consumption of water we need to hold the capacity of water as much required. Nowadays water tank are suitable for all types of atmosphere we live as old and civilized technique. Water is the basic need for all the living organisms to survive. Portable water is essential for good health of human beings. It is important to supply portable water to every individual and every community; hence it is very essential to store water. Water is generally stored in tanks and later the stored water is supplied to every community through pipelines. In this project, we have planned and designed a circular reinforced cement concrete tank. A circular water tank is manually designed. It is further analyzed using the premiere analysis software STAADPRO. The design and detailed drawings are presented in this project work. Limit state design method for water retaining structure was not adopted so far as liquid retaining structure should be crack free. However, this edition of Indian standard adopts limit state method mainly considering two aspects. Firstly it limits the stresses in steel so that concrete is not over stressed and in second aspect it limits the cracking width. Structure has been designed using the LSM, as the LSM gives less area of reinforcement of steel and hence the check for crack width has been done. Further to make the structure most economical STAAD. Pro is used. For quick cost prediction of tanks, this study therefore examines the cost effectiveness in terms of amount of materials. At the end of the project it concludes that total amount of concrete and steel used for construction of circular tank. Water tank are provides for the storage of water for drinking, irrigation, agriculture, fire suppression, paper industry and any more.
