| Summary |
In this paper, FEM, of which an unknown quantity is the coordinate value on a deformed body, is applied to geometrically nonlinear tension structure analysis. This method belongs to the displacement method, though an unknown quantity is not set as the displacement. The unknown quantity is a coordinates value on a deformed body. In this discretization formulation, a cable element and a membrane element are described. The computation examples are general shape analysis of cable structure and membrane structure of the HP type. It is shown that our method is a powerful means of tension structure analysis through the evaluation for the
discretization formulation and the numerical result.
