| Abstract: |
| In many practical engineering problems, the structural parameters and loads are uncertain. If they are not modeled, it is not sensible to analysis and design. Considering that the finite element method is commonly used in science and technology fields, a static interval finite element method based on the element is established in this paper, and a continuous beam structure is taken, as an example. From comparison of the numerical results with the results of Chen S H and Yang X W, it can be shown that the proposed method is effective. |
