ABSTRACT: The development of “DISDECO”, the Delft Interactive Shell Design Code, is described. The purpose of this project is to make the accumulated theoretical, numerical and practical knowledge of the last 20 years readily accessible to users interested in the analysis of buckling-sensitive structures. With the open ended, hierarchical, interactive computer code the user can access from his work-station successive programs of increasing complexity. Included are modules that contain Koiter’s imperfection sensitivity theory extended to anisotropic shell structures under combined loading. The nonlinear Donnell-type shell equations in terms of the radial displacement W and the Airy stress function F are used. The spatial dependence is eliminated by Fourier decomposition. The resulting sets of algebraic equations form a standard matrix eigenvalue problem. Initial results indicate that an interactive use of these simple modules can greatly facilitate the search for an optimal lay up of composite shells under combined loading.
