Stability of steel silo wall under axially symmetric buckling and initial curvature of the shell directed inwards
Abstract
Stability of steel silo wall under axially symmetric buckling and initial curvature of the shell directed inwards
Incoming article date: 16.05.2018It was considered the method of calculating the stability of steel spiral-bound silo wall under axisymmetric buckling under the influence of internal grain pressure is considered. The silo construction consists of short, cylindrical shells smoothed through the folds and having initial curvatures directed inwards. It was obtained the solution for determining the critical stresses of short shells.
