Article Preview

Abstract:

Based on the cable stayed bridge on Zhenshui Road in Xinmi City, structure calculation of die carrier and determination of construction pre-camber of its main girder were studied. Using the finite element method, the deformation of die carrier was calculated under the prepressing condition of supporting structure by ANSYS software. Considering the main influence factors, the calculated construction pre-camber was obtained and the construction pre-camber was determined. The comparison between the calculated camber and the actual measured camber of main girder was accomplished. It showed that the error was very small. This study shows that according to the calculated pre-camber, the determination of construction pre-camber is more reasonable. The linear control of main girder can attain excellent engineering effect. It has certain guiding significance for designing similar bridge to determinate the construction pre-camber of main girder.
