Abstract |
Recently, the plate girder bridge is offen designed a temporary bridge for underground roadway construction have not interrupt railroad operation. The integral support plate girder bridge which have longitudinal girder and cross-girder is improved workability and reduction cost and of construction time. The cross beam of the integral support plate girder bridge has a normal box shape to distribute load on the main girde to end both side girder. In this study, On the change to the web distance of the cross box shows characteristics of related to the stresses and displacements on the flange and web plate. Afterward, the various analysis contributed to the safety improvement of crossbeam of the integral support crossbeam plate girder bridge.
