Abstract

Dynamic analysis for free vibration characteristics of multi-cell structures by using the simplified grillage technique is described. The problems, such as adequate representation of shear lag effects and the torsional stiffness of the closed cells, are discussed. A comparison of the results obtained, for structures with different support conditions, with those obtained by the finite element method establishes the accuracy of the proposed method. The effect of the aspect ratio of the multi-cell structures on their natural frequencies is also investigated.
