Abstract: The special phenomena of reinforced concrete shell buckling is described on the basis of the latest results of research. The method presented takes into consideration the special properties of the reinforced concrete including, plasticity, creep, and quantity of reinforcement. Snap-through critical loads calculated by the described method are compared to the results of model tests and to the loads and critical loads of erected domes. The shell buckling stiffness was seen to be composed of two parts; the bending and the axial stiffness of the reinforced concrete cross section. The critical load is reduced by the plasticity and the imperfections. The critical load of the reinforced concrete shells decreases by the craks of concrete and increases by the reinforcement.
