Intze tank can be termed as improved version of cylindrical tanks and are used for large storage capacity.
As per IS 1893-2002 (Part 2), when a tank containing fluid vibrates, the fluid exerts hydrodynamic pressure in the form
of impulsive and convective pressures having curvilinear variation, on the cylindrical wall of Intze tank . For simplicity in
seismic analysis, the code suggests equivalent trapezoidal pressure distribution along the wall height. In the present
study, efforts are made to determine tension and moment coefficients using finite element method for the equivalent
hydrodynamic pressure distribution along the wall height, that are not available in the code. It is hoped that, these
coefficients will prove useful for hydrodynamic pressure design. Further, the comparison of results of hydrodynamic
pressure design is carried out by finite element method using STAAD Pro V8i.
