| Abstract: | Amodel RC arch with steel tube frame to simulate the construction procedure of Wanxian Yangtze River bridge whose main span is 420 m has been tested. The model scale is 1/10. In this peper,the stress and deformations measured in the arch construction steps of the model are compared with the theoretical values.Finally the ultimate strength test whows that there is Plenty safty margin for model arch. |
