Abstract:The analytical and numerical techniques applicable to the determination of an estimate of the buckling strength of rein-forced concrete shell structures are discussed. A brief resume of the most appropriate methods is presented. Both bifurcation and nonlinear techniques are included in the review. Attention is not restricted to only mechanics approaches such as developed within the aerospace industry. Particular attention is focused on the numerical techniques that allow consideration of shell structure configurations that include supporting members such as are employed for roof or other architectural structures. For reinforced concrete shells an influence of material characteristics must play a dominant role in the establishment of the buckling load. Imperfection sensitivity and other aspects that have a significant impact on the buckling load for some shells of aerospace configurations and loadings do not contribute to a corre-sponding level.
