Summary:

It is known that silos and other stock structures which are special structures have been

constructed due to many reasons such as to storage raw and processed materials or

industrial materials and making fill.

Many parameters such as material type, degree of jamming, filling velocity, height of

falling during filling, discharge type and discharge velocity, geometrical and mechanical

properties of stock structures affect the equilibrium conditions of stock materials. In this

case, it is clear that determination of optimum ones among design methods related to some

theories for design of each class making classification for stock structures.

The basic purpose of this study is to clarify some main methods using same symbols

systematically and to prepare some tables and charts which facilitate application of

developed a general approach after that putting forward its basic principles with

recommended method in Turkish Silo Code.

This study carried out for this purpose consists of three main chapters and an appendix.

Classification of real stock structures, stock materials, mechanical definitions, applied

loads on silo which is one of a real stock type are explained in Chapter One. Some theories

for estimation of material pressures during stable conditions and their comparisons, some

information related to material pressures during filling and discharging of silos, general

approach for stresses in stock materials, explanation of relations between this theory and

Turkish Silo Code and some tables and charts which facilitate application of method

defined in This code are given in Chapter Two.

Chapter three is reserved for conclusions and recommendations and this chapter is

followed by references, and appendix and curriculum vitae of author.

As a result of this study, it is shown constituent of recommended method defined in

Turkish Silo Code and some tables and charts which facilitate practical usage of this

method are presented.
