They may occur as the owpath changes, and their magnitudemay increase with the rate of discharge. typical silo with circular

cross section consists of cylindrical wall, top ring beam, bottom ring beam, and conical hopper. The capacity of the silo

may be expressed in parametric form as /H1 4d3Y Structural Considerations: Warehouse and Silo 2 Fig. 9 Resultant pressure on

The recommended inside diameters of silos are (: 1. For heavy grain (such as wheat): 6.0 2. For light grain (such as sunower): 1.0.0 The ring beams provided at the top and at the junction of cylindrical wall and hopper part are primarily designed for the radial forces, which introduce hoop tension or compres-sion. The vertical component of the loads at those levels are transferred to the wall or tothe supporting system. Conical hoppers are essentially subjected to only meridional and hoop tensions. 2 Gupta and Bhattacharyya 3.5 Optimization Scheme Several optimization methods have been developed for solving different types of problems. The optimization techniques are useful in nding the minimum of function of severalvariables under prescribed set of constraints. The mathematical programming basicallyinvolves the approach of general method for expressing constraints of many types and the explicit use of an objective function, such as minimum weight, minimum cost, or other. While stipulating constraints, the aspects assumed are that every member shouldbe optimally stressed and deformations will remain within specied threshold. The prob-lem of optimization of silo is related to various parameters, as has been observed in theforegoing discussions. 4 DESIGN AND DESIGN AIDS FOR SILOS 4.1 Form and CapacityA few examples a
