Design and Analysis of Silo

Abstract

Bulk storage tanks are very important for industrial and agricultural facilities. The value of these tanks to society exceeds by far the economic value of the tanks and their contents. This is because the failure of tanks and their accessories is not lim- ited to the immediate danger to nearby human lives, but also to a large extent leads to serious consequences and very likely to long-term environmental damages.Thus to prevent failure of the silo it must be design properly. This report contents designing of the silo as per various applicable code and standards. The silo is designed for various types of load acting on it e.g. dead load, live load, wind or seismic load, load during lling and discharging of bulk material etc.. Stress calculation has been done for Silo having storage capacity of 580 m3 for storing plastic pellets. This include di er- ent kind of stresses developed in silo i.e.circumferential stress,axial stress,equivalents stresses.Finally all stresses are veri ed by allowable stress values of construction ma- terial according to standards.Axial buckling and circumferential buckling stresses are veri ed as per DIN 18800 part 4 1990.
