Depending on their geometry, material and boundary conditions, shells can experience a reduction in the buckling load. Several methods settle the instability in concrete shells, in particular the one exposed in the IASS Recommendations, which contains some curves reflecting the influence of the initial geometric imperfections in the buckling load for simple geometries (spheres and cylinders). In recent decades, different revisions of the Recommendations have been carried out, however new curves for geometries with more complexity have not been stated. In this study, a method is implemented to determine the imperfection sensitivity factor in the case of shells with geometries such as a spherical dome, barrel vault and doublecurvature ruled surface. © Civil-Comp Press, 2010.
