Structures used for storing bulk solids are called bins, bunkers, silos, or tanks. There is no generally accepted definition for these terms, shallow structures containing coal, crushed stone, gravel, and similar materials are called bins or bunkers and tall structures containing materials such as grain, cement and wheat are usually called silos. Elevated silos generally consist of a conical roof, a cylindrical shell and a conical hopper and they could be elevated and supported by frames or reinforced concrete columns. Circular silos (both steel and reinforced concrete) are used to store material in various industries like cement plants (clinkers), power plants( raw coal), oil and gas industry (sulfur pellets) etc. Elevated steel and reinforced concrete circular silo for storage show performance in earthquake reinforced concrete silo stability increases by using shear wall but loss of steel silo in earthquake stability increases using steel panel on opposite side Displacement of structure decreases in case of shear wall panel and stiffness increases. In the present study, The load calculations, load combinations, load assignment, earthquake parameters, and analysis have been represented, and the results from this analysis are represented and compared the result outputs of all the models are displayed, max absolute stresses and max shear stresses developed in each model are represented via contour diagrams, tables, and graphs, the values of minimum required Ast for beams and columns are mentioned. The max lateral displacements obtained for the critical load case/combination are noted down for each model at heights of H25, the following is the maximum of nodal displacements to height H25 of constant diameter of D5 as 9.133 mm at nodal point 73. Keywords: RCC, Silo, Displacements, Maximum Absolute Stresses, Maximum Shear stresses, IS: 456-2000, is: IS 1893-2016, STAA
