| Abstract: | Based on the analysis of the relevant welding shrinkage deformation data, the suitable formulae for welding shrinkage were deducted and were well combined with the utilization of the shared foreign welding software. In the light of the special structural types of the integral gusset plates of Dashengguan Changjiang River Bridge in Nanjing, the welding shrinkage amounts for the plates were appropriately preset and the structural dimensions thereof were brought under effective control. |
