Annotation: In the article the basic questions of reliability of increasing of silo steel funnel conic casing coal storage have been considered. Basic approaches to research of the tensional and deformed state of metal silo funnel have been considered. The analytical calculation of the tensional and deformed state of silo funnel has been carried out with using of the idealized calculation chart on methods, offered in normative documents has been fulfilled. The numeral calculation of the tensional and deformed state of silo funnel has been fulfilled by means of complex account SCAD. The influence on the bearing ability of conical casing of additional supporting joints in kind of supporting ring leaned along the perimeter on bars has been considered. The features of changing’s of the tensional and deformed state of casing are considered while partial elements tearing of funnel fixing to the reinforced concrete cylindrical part of silo. Thus, the variants of both freely hanging conical casing are considered and supported with additional leaned constructions. On the basis of the fulfilled analytical and numeral calculation conclusions have been made and recommendation designing have been given.
Keywords: metal construction of silo funnel, regional effect, tensional and deformed state, analytical and numeral methods of calculation.
