THE COOPERATION BETWEEN A 3D MODEL AND ANALYSIS SOFTWARE FOR RAILWAY VIADUCTS

Abstract

 Much effort is underway to realize the concept of Building Information Modeling (BIM) in the building industry. However, in the civil infrastructure domain, the BIM concept has not been adopted yet in practice because few engineers are accustomed to 3D models. As the interaction between 3D models and structural analysis software packages is important in the design phase, two structural analysis software packages for railway viaduct were selected to investigate the linkage between 3D models and the packages. Furthermore, a method of the interaction with ST-BRIDGE, which has been developed by the Structural Group of buildingSMART Japan was demonstrated. Finally, issues related to 3D modeling were discussed.
