Sažetak
The paper deals with the features of silos calculations as shells of rotation under asymmetric semi-uniform load. In accordance with the equation of equilibrium by using the momentless theory, the expressions for maximum value of linear longitudinal efforts in radial and meridional (longitudinal) direction and linear shearing force have been obtained. Analysis of design factor series of linear efforts and shearing force has been carried out in the paper. The opportunity of using the momentless theory to evaluate changes of linear efforts in radial direction and shearing forces has been presented. The quantitative assessment of a normal tension in laminas of silo body from the influence of maximum linear efforts and their connection with the tension from the pressure of the bulk material at the top of the capacity have been given. Full radial and contacting displacements of the capacity in the plane of cross section from the element of the wind load have been defined.
