View Product Description

A box girder, otherwise known as tubular girder, is a girder that forms an enclosed tube or hollow box like structure with multiple walls. The box is typically rectangular or trapezoidal in cross-section. Box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport.

Steel twin box-girder bridges are one type of box girder bridges, and considered an attractive option in most of the world because of their basic design, simple form, and ease of construction.

When the bridge depth is smaller than 1/6 of the bridge width, then a twin-cell or multiple cell is a better choice . However, even for wider bridges with small depths, the number of cells should be minimized because there is not much improvement in transverse load distribution when the number of cells of box girder is increased to three or more.

For two-cell box girders, there are generally two arrangements. The first one is that independent cells are connected by their top flanges only while the other one is that the cells are connected both at the top and bottom flanges. From the structural point of view, it is recommended to adopt the second arrangement. For the case of cells connected by top flanges only, their flanges are heavily stressed in the transverse direction owing to flexure which cannot be effectively distributed across the cross section.

Advantages of using Box Girder

*Single or multi-cell strengthened steel box Girder Bridge have been proposed and broadly utilized as monetary effective answer for the over intersections, under intersections, level division structures and viaducts found in current expressway framework.

*The expansive Torsional unbending nature of the case girder’s shut cell segment gives structures underneath is more tastefully satisfying than open-web sort framework.

*If there should be an occurrence of long traverse spans, expansive width of deck is accessible to suit pre-stressing links at base rib level.

*Insides of box girder scaffolds can be utilized to suit administration, for example, gas channels, water mains and so on.

*For huge ranges, base rib could be utilized as another deck obliges activity moreover.

*The support of box girder is simpler in inside space is straightforwardly available without utilization of framework.

*On the other hand space is hermetically fixed and encased air might be dried to give a non-destructive air.

*It has high auxiliary effectiveness which minimizes the pre-stressing force required to oppose a given twisting minute, and its extraordinary Torsional quality with the limit this provides for re-focus capricious live loads, minimizing the pre-stress required to convey them.
