| Abstract: | In order to meet the designed requirements of the Hemaxi Bridge in structural strength and linearity,a numerical analysis is made of the construction process with the ANSYS software in the paper,with the pre-stressing methods and the characteristics of the critical Element introduced.It is found that the sectional stress,cable force and linear shape of the ANSYS analysis results are totally in agreement with the measured on-site results,which proves that the ANSYS software can be used to simulate and analyze the construction processes of partially cable-stayed bridges. |

| Keywords: | partially cable-stayed bridge pre-stressed concrete structure equivalent load method three-dimensional beam element simulating analysis |
