Abstract:
In this study, the performance of a laterized concrete cylindrical shell for storage of food grains was investigated. The structural characteristics values of laterized concrete at optimum mix proportion were applied in performing the static analysis of the cylindrical shell structure under the action of food grain pressures using Pasternack’s equations formulated on the basis of theory of shell of revolution. The reduced equation of static equilibrium was solved by the initial- value method. A generalized solution of cylindrical shell made of laterized concrete was obtained and used to evaluate the performance of the structure through the determination of deflection and stresses. The results of the analysis indicate that the maximum stress developed due to soybean grain loading is greater than the material strength in silo thickness of 100mm, 20m in diameter and 8m in height. The wall thickness of 150mm was found adequate for silo of the same size.
