The purpose of this paper is to present a state-of-the-art review of the stability of reinforced concrete domes and hyperbolic paraboloids aimed principally at presenting useful information to the designers of such shells. Analytical results, experimental results, and applications to design, together with appropriate references, will be reviewed and summarized for each of the following shell types: (1) spherical domes, (2) translational and other double curvature domes, (3) hyperbolic parab-loids, and (4) groin vaults. The effects of the following important parameters on the buckling of reinforced concrete shells are discussed: (1) geometric imperfections, (2) creep, (3) cracking of concrete and amounts of reinforcement, and (4) material non-linearity. A design approach is suggested to account for these effects. A number of examples of existing large span reinforced concrete shells are cited to illustrate the range of dimensions which have been used successfully in the past.
