| Abstract: | Taking a through bridge with rigid suspender and tie-arch for example, the space stability is analyzed by means of finite element program. The four simulation schemes on the stability of rigid suspender are calculated in details. It is shown that the results from calculation are of great difference in simulation programs. Reasons for such difference are analyzed and correct methods proposed in this paper. |
