| Abstract: | The meaning and characteristics of BIM technology are summarized briefly. The model of PC continuous box-girder bridge stiffened by steel truss is established with Autodesk Revit software platform based on parameterized libraries of bridge pier,box girder and reinforcement. The library models can be modified automatically. The graphics format conversion of the BIM model is discussed and the dynamic roaming demonstration is implemented based on Lumion software platform, which provides 3D visualization and new ideas for detailed demonstration of such complex bridge structures. |
