| Abstract: | The temperature distribution, temperature load, and the stress resulted from temperature variations were measured during the construction monitoring of an open spandrel rigid-framed arch bridge with box cross section. Based on the measured data, the stresses resulted from temperature variations of this kind of bridge and its change of structural system are discussed in this paper, and a practical exponent function formula to fit the temperature distribution of box beam is recommended. |

| Keywords: | arch bridge temperature variation rigid-framed arch with box section monitoring in site |
