| Abstract: | In this paper the stability of Zhengzhou Yellow River main bridge of Beijing-zhuhai freeway is studied. The finite element analysis software ANSYS is applied to set up the three-dimensional finite element computational model of the concrete-filled steel tube arch bridge. Its safety factors of stability are calculated and their corresponding buckling mode are analyzed. The result reveals that the stability of Zhengzhou Yellow River main bridge are safe. The result may offer the related technical parameters and basic data for the construction and the health detection and maintenance in its working conditions. |
