Abstract
Influence of external side elements on the condition of the cylindrical mesh shell
Incoming article date: 13.12.2021The condition of a metal cylindrical mesh shell with external horizontal trusses is investigated. The basic principles of forming the structure are considered, taking into account the use of a support rib to align the faces of a mesh surface. The analysis of important force factors and deformation parameters of the reinforced shell is carried out taking into account all possible combinations of loads. The regularities of the system operation are determined and the influence of the location of the support trusses on the behavior of the structure is estimated. Vulnerable areas with maximum longitudinal forces in the elements and the greatest displacements of nodes were identified. An increase in stiffness outside the shell plane in the transverse direction was obtained and a positive redistribution of forces over the surface was recorded. An acceptable result was established from the point of view of ensuring the stability of the structure and the increased resistance of the shell to deformation was noted.
