    Abstract. The problems of choosing the optimal design of a steel silo according to economic and technical indicators are analyzed. The design features of the silos with a flat base are given and the schematic diagram of the metal elements operation of the silo of this type as part of the overall design is described. It is emphasized that when designing the silos it is necessary to have the skills and experience of calculating these structures due to the specifics of their design. The calculation of metal structures of the silo is considered. The method of determining the loads acting on these structures in accordance with the current design standards is shown. The results of determining the efforts in wall panels of the silo obtained manually and with the help of finite element software complex LIRA SOFT 10.8 are presented. The estimation of bearing capacity of elements of metal designs of the silo and their connections among themselves is made. On the basis of the calculation results and survey materials, the causes of the collapse of the silo metal structures are analyzed, photos of the consequences of the collapse are presented. Recommendations on prevention of emergency situations connected with mistakes of silos designing are made.
    Key words: steel silo, metal structures, progressive collapse, strength, forces, stresses, finite element software package.
