| Abstract: | On the basis of the shanghai middle ring road engineering, the mechanic characteristics of single box and multi-cell box girder with curved bottom and a large width to span-length ratio under the transverse prestress force are mainly discussed in this paper. A finite element model is built to analyze the transverse prestress spatial effect .The effects of the transverse prestressed tendons in the cross beam and top plate are discussed respectively and the distribution regularity of transverse stress in transverse and vertical direction of structure is also discussed in this paper. All of this can be used as reference in design. |
| Keywords: | curved bottom single box and multi-cell transverse prestress spatial analysis |
