Abstract: |
Dong XUProfessor Tongji University Shanghai, China xu_dong@.tongji.edu.cn Dong XU, born 1966, received his doctor’s degree from Tongji University. Yuan SUNPh.D. Candidate Tongji University Shanghai, China sunxiao_1981@126.com Najin Bridge, located in Lasa of China, is an extradosed bridge with three towers and with (70+117+117+70)m spans. Turning radius of all saddles in the main tower of this bridge is 2.5 m. Now minimum radius of the saddle at extradosed bridges in China is 2.8m. For the security and reliability of the bridge, we researched and analyzed stresses of saddle segment by the ANSYS software accurately, and carried on the full-scale model test. Some suggestions are proposed for this bridge. |
