Abstract: In article the basic questions reliability increasing of the conic metal funnel of the bunker have been examined. The main approaches for researching of the tense-deformed condition of the bunker metal funnel have been considered. The analytical calculation of tense-deformed condition (the bunker funnel) with the idealized account scheme using due to the method offered in BNandR II-23-81* “Steel structures and designing norms and the instruction on calculation and designing of the reinforsed-concrete, steel and combined bunkers has been carried out”. The numeral calculation of the tense-deformed condition (the bunker funnel) using the finite element casing of a telescopic structure influence considering the marginal effect in places of overlapping by means of account complex SCAD has been fulfield. The analysis of the tense-deformed condition momentless of the conic casing without taking into account the bending moment, and considering its influence stipulated by overlapping in places of telescopic side-bars function and caused the factor of the marginal effect phenomenon. On the basis of the fulfilled analytical and numeral calculation conclusions and recommendations as for calculation and designing have been done.

Keywords: a metal design funnel the bunker, the marginal effect, the tense-deformed condition, momentless an casing of a telescopic design, analytical and numeral methods of calculation.
