| Abstract: | It is found through researching on space thin-walled structure that the application scope of the element stiffness matrix in the actual computation by using the matrix displacement method is different from using the finite-element method.The analysis of physical phenomenon derived from this question was carried out,which may provide the foundation for the calcuation of the thin-walled spatial structure. |
