Abstract
Analysis of liquid containing tanks differs from other structures because during seismic excitation, liquid inside the tank exerts hydrodynamic force on the tank walls and base which makes the analysis a complex one. The objective of this research is to determine hydrodynamic pressure distribution on rectangular tanks of various geometries considering impulsive and convective components of liquid mass. The focus is also to develop design charts to analyse the effect of geometry of tank on design seismic forces and sloshing. To get a better picture, a comparative study of Draft IS 1893 Part 2, ACI 350.3 and Eurocode 8 for rectangular shaped tank has been performed. Further, the differences in the magnitude of shear and moment at base as obtained from static (IS 3370 IV) and dynamic (Draft IS 1892 Part 2) analysis of rectangular shaped tank have been evaluated which highlight the need for us to mature from the old code to a newer code, which is more accurate and reliable.
