   Abstract / 摘 要    

The fabrication and assembly technology of the Sava bridge in the city of Belgrade is introduced in this paper. Sava bridge is a 6 span, continuous superstructure with an overall length of 929 meters between deck expansion joints. Safe and reliable assembly jigs are applied in both workshop and bridge
site. Welding shrinkage and welding deformation are considered during assembly. European standards are strictly followed during the whole processes. This paper can be reference for similar project as well.

   Key words / 关键词
