Annotation: The problems of reliability of large-span suspension roofs have been analyzed. The fundamental approaches to regard of joints reliability in designs of reliability of suspension bar roofs have been described. The bearing joints of sheeting of curved and rigid filament to the external and internal outline, interstitial joints of the top and lower chords of bearing filament, sheeting joints of vertical and horizontal connections to the bearing filaments of the roof have been accepted as the designed data. The logical and probabilistic methods of estimation of joints reliability and methods based on the mathematical statistics have been accepted in the analysis. Carried out structural design of reliability of joints of suspension roofs has shown that they are mainly described by sequential schemes including parallel connections of dependent elements corresponding to multi-elementary connections selected in store. Correlation regard between the elements of structural schematic drawings of joints in consequence of generality of intensification and strength of steel allows to reduce quantity of elements in the scheme and increase resulting estimation of reliability.
Keywords: space and bar suspension shell, curved and rigid filaments, joint, reliability indices, stressed-strained state, logical and probabilistic methods.
