Abstract
Investigation of parametric dependencies in the safe operation of cylindrical mesh shells
Incoming article date: 03.11.2024The article discusses the parametric dependencies of cylindrical rod shells in terms of their effect on the state of force and movement of nodes in the grid area. Critical condition factors are analyzed, taking into account the degree of cell filling and the magnitude of the discrepancy between the specified characteristics. The analysis of the formative parameters is carried out and the rational limits of their possible use are established. The factor of taking into account the size of the cell with the location of the rods inside the faces has been introduced. The basic ratios are obtained and the degree of sensitivity of the calculated models to changes in geometric shape is estimated. The limiting angle of the outlined circle has been found, beyond which the operation of the structure is impossible. The level of dangerous increase in the total parameter along the arc at the lowest possible height of the structure has been determined.
