These structures, subjected to external pressure may be involved in instability phenomena, both in elastic and in elastic-plastic range. As well known the elastic stability is one of the most dangerous collapse modes, owing to its sudden taking place; moreover it is heavily influenced by geometric imperfections, caused by the fabrication processes. It is then necessary to evaluate the influence of these defects in the collapse pressure reduction. In this study a double theoretical- experimental investigat
