Analysis on Transverse Effect of Urban Elevated Bridge with Broad Box Girders of Arc Bottom |
| |
| Abstract: | Taking engineering of broad box girder of arc bottom in 2nd phase of Shanghai Humin Elevated Road Works as an object of study, analysis has been made on sectional transverse effect of box girder under dead weight and external load with finite element method, and on the influence from transverse beam rigidity of pier top, transverse distance between the bearings, and web thickness on transverse stress, for reference of the design of bridge structure. |
