- Span Continuous Rigid Frame Bridge The Temperature Effect

The application of tall-pier and long-span continuous rigid-frame bridges is apparently wide, and it had becoming an important bridge style in modern communication engineering. However, because of the domestic and foreign design codes concerning the bridge temperature effect is disunity, the results according to the different norms are various. Based on the Xu Shui Gou Bridge in ShanXi He yang, calculate the sunshine temperature effect of the upper box girder , analyze the difference between results on each norms, and educe the upper box girder' s distributed regulation about temperature stress and temperature deformation for the sunshine temperature effect; Select the different day radiates' direction, calculate the sunshine temperature effect of the lower part tall-pier with thin wall, and educe it' s distributed regulation about temperature stress and temperature deformation for the sunshine temperature effect; Compute the temperature effect influence of year of the whole bridge finally, and carry on the comparison with the influence of the sunshine temperature effect.The research founding is hoped to provide the certain theories according to and the technique reference for solving the problem of temperature effect in designing of the tall-pier and long-span continuous rigid-frame bridges in the later, and provide the certain rationality opinion for the related norm standard of further perfect, and to accelerate the development and perfected of the temperature effect theories of the tall-pier and long-span continuous rigid-frame bridge.
