Impact of Varying Height to Diameter Ratio of Intze Tank on Different Component of Tank

Intze tank is an important overhead water storage tank, there for it is necessary that it should be constructed keeping in view its economy. To obtain economical design of tank, the proportion of container such as, staging container diameter ratio, height of cylindrical wall container diameter ratio and horizontal angle of dome have been varied as well as no of column for design of staging .To achieve this objective 15 different depth to diameter ratio of Intze tank. For this purpose a computer program in Microsoft excel has been developed. In Microsoft excel program continuity correction have been work out .The design of container is carried out by working stress method but staging is carried out by using limit state method. To get the economical design of Intze tank horizontal angle of conical dome should be 'less than 45°, ratio of height of cylindrical wall and container diameter ratio should be between 0.3 and 0.35.0n the other hand staging container diameter ratio effects the economy of higher capacity of tank only.
