| Abstract: | Temperature field of box-girder due to solar radiation was measured of a high pier and long span continuous rigid-frame bridge,its longest span reaching 200m.,a regression analysis of the temperature difference using the least square method,and the fitting curve of vertical and horizontal nonlinear temperature difference distribution of box beam in the sunshine are obtained in this paper.A calculation model for the bridge using finite element method has been built,and the influence upon the temperature difference was analyzed. |
