| Abstract: | The geometrical precision of the flat steel box girder used as the stiffening beam of the suspension and cable-stayed bridge is mainly determined by the assembly precision and the welding deformation control. It is very difficult to control the welding deformation of the complicated structure. In this paper the structural characteristics of steel box girder used in the Second Nanjing Yangtze River Bridge and the test results of the welding deformation of its main welding seams are introduced. On the basis of these results the empirical formula is founded through statistics and analysis. The systematical measures of welding deformation control are presented summarily in this paper. |
