To calculation the reliability of the body sheets of the storage capacity

The article deals with the separate questions of the stochastic calculation of the body sheets of steel cylindrical silo capacities. Particular attention is paid to the quantitative evaluation of statistical parameters of the particulate solid characteristics: unit weight, angle of internal friction, lateral pressure ratio and wall friction coefficient. Their analysis and comparison in various regulative documents is represented. The expression for calculating the random value of the horizontal pressure of the particulate solids is formulated and the curves of density and the distribution function of the given quantity are constructed for the case of considering the correlation dependence of the statistical parameters of the particulate solid characteristics and when these quantities are completely independent. Also it is presented an expression for calculating the random value of the critical factor of the sheets of steel storage capacity with the following statistical of the given quantity with different coefficient values of the steel variation. Conclusions are made accordingly to the influence of the coefficient of variation at the value of probability of the failure-free operation of the body sheets.
