| Abstract: | The design of the south bridge over Xiangjiang River in Changsha City is introduced. By using spatial finite element analysis, a stress analysis for the structure of V-type support is conducted, the iso-stress traces of the various parts of the structure are plotted, and problems that can not be found in the routine analysis for internal forces are revealed, which provide a reliable basis for rationally determining types and design of the structure of the V-type support. The suitable method of construction is introduced last. |
