Abstract: Intz tank is an important overhead water storage tank, there for it is necessary that it should be constructed keeping in view its economy. The main aims of this paper are hydrostatic analysis of Intze water tank, To obtain economical design of tank, the parametric study must needed, for this purpose we can vary the proportion of container such as, staging container diameter ratio, height of cylindrical wall to diameter ratio and horizontal angle of dome have been varied as well as no of column for design of staging .To achieve this objective 4 different depth to diameter ratio of Intze tank consider for analysis on staad pro software and comparative results obtained in term of principal and Von mises stresses on cylindrical wall. Maximum shear force and bending moment on beams and node displacement. For the parametric study of Intze tank horizontal angle of conical dome should be 45°, ratio of height of cylindrical wall to diameter ratio should be kept 0.5, 0.8, 1 and 1.5. with constant volume and height of staging. Keywords: Intz tank, Parametric study, Staad pro.
1. INTRODUCTION Intz water tank most common type of elevated water retaining structure to store water as per locality demand. It consists of cement concrete because imperviousness of concrete but as we know that due to hydrostatic pressure, the cylindrical wall under tensile stresses, and concrete weak in tension. So, it is very essential to keep this tensile stress within the permissible limit which depends upon the height of the cylindrical wall and diameter of the container. In this paper, we use a different ratio of height to diameter ratio of container to check the stresses' behaviour on the cylindrical wall with the same quantity of water.
2. OBJECTIVE OF WORK 1. Perform Parametric study of Intz water tank with varying the height to diameter ratio of a cylindrical c ontainer with the same volume and height of staging by using Staad pro software. 2. Find out the variation of Principal and Von mises stress on cylindrical wall with same thickness.
3. METHODOLOGY 1. Design of Intz tank by using IS 3370 & IS 456: 2000 with different Height to Diameter ratio. 2. Create a Model with the help of Staad pro software and Apply the same load on the tank wall which is obtained in Manual Calculations. 3. keep the thickness of the cylindrical wall is constant for all Model with same volum e. 4. Prepare a comparative chart of all output quantities such as Principal and Von mises Stresses on Cylindrical plate, Node displacement in all directions, support reaction and shear force and bending moment of the beam and circular girders.
