To Study The Analysis, Design and Behavior of Corrugated Steel Silo

The paper deals with Analysis and Design of large cylindrical steel silos composed of horizontally corrugated sheets with vertical stiffeners. The 3D FE calculations were carried out with the commercial finite element code " STAAD Pro. software ". Usually in India, we are using IS and ACI codes for analysis and design of steel silo, but in no one they have describe about corrugated steel silo. It is important to know about the change in grain pressure and wall thickness, when we are using corrugated sheet instead of plain sheet during analyze and design the silo. In this paper we have calculated grain pressures and external load by using IS codes and other literature, then prepared geometry and analyzed it on STAAD Pro. Software to compare the result of hoop stress in vertical wall. Value of hoop stress in manual calculation and in STAAD Pro. are almost matching, except in the case of top and bottom plate. It shows that our assumptions while modeling the silos are correct.
