Within the framework of the DESICOS (New Robust DESign Guideline for Imperfection Sensitive COmposite Launcher Structures) funded by the European Comission, the buckling bahviour of imperfection sensitive shell structures is investigated. Due to the high effect of imperfections on the load carrying capacity of shell structures subjected to axial compressive loads, imperfections have to be considered in the design phase. For this purpose, empirical relations, mostly derived with the 1960s such as the NASA SP8007 Guidleine, are applied. With the DESICOS project, it is aimed to develop new design guidelines for unstiffened and stiffened shell structures, leading to structures having beneficial properties in terms of lightweight design purposes.
