ABSTRACT: The buckling strength of a thin cylindrical shell is important in many applications in civil engineering. On the one hand, current design rules are principally based on an empirical interpretation of test data and hence very simple loading conditions are applied. On the other hand, experimental and theoretical observations show significant stress non-uniformity and hence a deviation from the buckling strength expected under uniform load. Reliable quantification of this effect is still challengingly difficult.
This paper explores a typical thin cylindrical silo shell under localized axial compression. Two different buckling phenomena are identified with corresponding, and distinct, buckling mode forms. The influence of geometric imperfections on the buckling strength of the shell is also considered.
