| Abstract: | In this paper a composite element is proposed for analysing double shell structures. It consists of upper and lower flanges and four closed webs, The webs are treated as beams with considering the shear effect, and the flanges are treated as membrane elements and the effect of stiffeners is taken into account, The four nodes of the composite element are located at the joints of adjacent beams. This element reflects not only the bending effect of webs but also the shear and Poisson's effects of flanges, It is an effective element for the analysis of single shell structures as well as double shell structures. |
