| Abstract: | The software ANSYS is used to establish the finite element models for both the Wujiang River Rigid-Frame Bridge and its form travelers used for cantilever construction,and is also used to make the loading and simulation calculation of the process of the construction.The displacement of the girders of the Bridge under various load cases has been obtained and references to the determination of pre-cambering and smooth closing of the Bridge are provided. |
