| Abstract: | Considering the spatial effect of broad box girder subjected to engineering loads,a fine FEM model was established,which was used to study the mechanical distribution of broad box girder under transverse prestressing forces.This study was carried out on the basis of the mechanical distribution of broad box girder subjected to dead load.Finally,some valuable suggestions were proposed. |
| Keywords: | broad box girder transverse prestressing force spatial effect |
