| Abstract: | It is difficult to analysis concentrated force by common BEM. In this paper, A new method is berived to solve the problem concerned concentrated force. The examples show that. the method is efficient. With high accuracy and less elements, the special BEM can reflect the results of concentrated loads efficiently. |
| Keywords: | Concentrated load BEM. |
