Compression stiffened panels are reinforced skins that are mainly subjected to axial compressive load and are widely used in aerospace structures. Iterative design loops are the common methods for these types of structure. Design methodology based on structural index concept is a coupled design and analysis method. In this method detailed design of the compression stiffened panel is fully accomplished based on the key parameters of structural index and material properties of the panel. The complete design is obtained in single stage in an analytical and explicit manner. In this paper the design methodology of stiffened panel using structural index concept that could be applied on selective configuration of compression stiffened panel (including selection of stiffener type and the type of panel: integral or skin-stringer) is analyzed. The results are extracted and modified from two different approaches to manage the results of common iteration methods that are currently used in the preliminary sizing of stiffened panel. This procedure could be regarded as a near optimum design and therefore would be more conservative with respect to common methods. Final results of the derived methodology are compared with reported and FEM results. The results could be considered an acceptable design; furthermore, they can be used as an appropriate starting point in numerical optimization methods. [ABSTRACT FROM AUTHOR] |
