Calculation of Reliability of Hangars for Parking and Maintenance of Vehicles

Thin shells are often used for roofing of large-span constructions including hangars for vehicles. This paper considers the approach to study of strength and stability of such structures.A geometrically nonlinear mathematical model of deformation of double curvature shallow shells reinforced with ribs is considered. The model is represented with dimensionless parameters. The algorithm is based on the Ritz method and iterative processes.Analysis of strength and stability was held for six types of shell structures of different radii of curvature and thicknesses with a different number of reinforcing ribs and made of different materials that can be used as roofing of hangars for parking and maintenance of vehicles.
