Failure modes and buckling capacity of thin cylindrical reinforced cementitious shells under axial compression

High performance cementitious composites have made possible the manufacturing of thin cementitious shell structures which are prone to buckling. Perhaps the most comprehensive design procedure for such shells is provided by the design recommendations issued by the International Association for Shells and Spatial Structures (IASS) which, however, are inconsistent with the modern European design framework. The scope of this paper is to contribute to the development of a design methodology similar to the one recommended by Eurocode 3 part 1-6, which is based on a capacity curve that represents all the possible failure states. In this respect, the capacity curve of an axially compressed cylinder is produced by geometrically and materially nonlinear analyses for different fabrication quality classes, which are in the sequel approximated by parametric capacity curves based on parameters determined following the concept of Eurocode 3.
