| Abstract: | The delimiting way of three dimensions finite element nets,which is suitable to the peculiarity of the structure of the floating globe platform, is finded in this paper, and the relative program of the informations of element and nodes is designed. The displacements of this structure are calculated by ADINA program, and the rigidity is analysised. The result of calculation is compared with the experimental data, and the responsibility of the result of this paper is ensured. |
