Bridge structure is influenced by external temperature inevitably, and hyper static structure, especially cable-stayed bridge, has complicated stress response on the effect of temperature action, which greatly increases the difficulty of structure stress analysis. For the sake of research on the influence degree of temperature action to large span concrete cable-stayed bridge girder, take Luzhou Taian Yangtze River Bridge as an example, the temperature field and temperature stress of girder are analyzed using measured data from health monitoring system. The results of finite element simulation experiment demonstrate that, the influence of longitudinal temperature distribution must be considered in large span bridge design, and the measured data of bridge health monitoring system installed are accurate.
