| Abstract: | Taking Cao＇e River Bridge as engineering background, this paper uses finite element method to analyze the all time temperature field of concrete filled steel tube arch rib in the summer under three working conditions, fits the temperature function of cross-section finite element model, and studies the structural behavior of arch rib under the action of nonlinear temperature difference. Some useful conclusions are obtained in order to instruct this type of structure design. |
