the buckling desing of reinforced concrete shells has to guarantee that local buckling is prevented overall. As model tests how. Buckling always begins locally, and in the case of cooling tower shells, the effect of boundary conditions is less than the effect of intial impeerfections. Cooloing tower shells buckle locally in the presence of even slight imperfections and absence of deformation control. In addtion to shell geometry and thickness, stress state is the most important parameter affecting buckling. Critical stress states obtained under axisymmetric loading can be extended to non axisymmetric loads like wind. Numerical results show the substantial effect of the nonlinear biaxial material law of concrete on buckling behavior. The buckling problem of reinforced concrete shells cannot be isloated from the material and its load-carrying behavior.
