Abstract
Investigation of the parameters of reinforced cylindrical mesh shells within the limits of stability
Incoming article date: 13.10.2024The article considers the parameters of rational use of additional support faces of reinforced cylindrical mesh shells. The assessment of the features of shaping has been carried out and the choice of the topology of surfaces within the limits of ensuring the stability of the structure has been justified. Recommended ratios of overall dimensions are proposed and corresponding calculation models are formed. The criteria for determining the sensitivity of the grid are given, taking into account additional support faces and the fulfillment of the conditions of limit states. A range of acceptable values of curvature and geometric parameters for the creation of reinforced cylindrical mesh shells has been obtained. The effect of increasing stiffness and increasing height on the performance of the mesh surface is analyzed. The characteristic patterns of changes in nodal deviations and internal force factors of vulnerable zones are revealed.
