| Abstract: | The buckling and postbuckling behaviour of shell assemblies are studied,in which the conversion of the generalized displacement of nodes on intersection line of two shells and modification of stiffness maxtrixes are discussed. The concrete conversion matrixes are shown in this paper. The shell assemblies with L,Z,H section are analysized and computed and good results are abtained. |
