Abstract
The aim of the research. To analyze the stress state of structures of ribbed-ring domes of different heights during overhang erection. The domes have spherical metal frames and a support contour of the same diameter. Due to different heights, the steepness of the geometric shape of the domes changes. The study is devoted to establishing the relationship between the stress state of the frame and the steepness of the dome when mounted. It was investigated how the height of the ribbed-ring dome affects the stress state of its frame during overhang mounting process. Methods. Computer models of design frames of ribbed-ring domes of different heights made of steel I-beams were developed. Based on design models, a sequence of assembly models for incomplete frames was created for different stages of installation. Both for the design and for all installation models of dome frames of different heights, computer calculations were performed for the effect of the load from its own weight. As a result of calculations for all domes and at all stages of installation, deformations and stresses in the meridional ribs were determined, which were compared with the design diagrams. Results. Comparative graphs of deformations of dome frames and diagrams of changes in the degree of use of steel strength in meridional ribs at all stages of mounted installation are obtained. Comparative graphs of installation and design stresses in the meridional ribs on different tiers for all stages of mounted installation are also shown. The assessment of the installation stress states is given, their inevitability and the degree of influence on the stress state of the dome frames are noted.
