Silos are containers used for storing bulk solids. Although there is no generally accepted definition for these terms, shallow structures containing coal, coke, ore, crushed stone, gravel, and similar materials. Silos are special structures subjected to many different unconventional loading conditions, which result in unusual failure modes. In this present study pressure calculation is carried out by Janseen’s theory and Reimbert theory for static condition and additional pressure due seismic action is calculated by Theoretical approach. Base shear force generated at bottom of silo is compared with using IS 1893-2002, ASCE 7-05, AIJ 2010. Calculation is completely based on respective codal provision applied to Indian seismic zones, site condition etc.
