A Box girder bridge is a multi-span steel truss bridge/prestressed concrete characterized by a very large, hollow box-shaped steel beam that is used to span between two piers. The Box girder bridge design consists of three . This study is based on a proposed steel box-girder bridge that would be part of an urban elevated system. The upper structure of the main beam is a 48 m +60 m +48 m steel box girder. The full width of the bridge is 13.5 m, and the steel box girder adopts a single box double chamber section. The bridge layout is shown in Figure 1.
The analyses of the example bridge show that the flexural failure of the deck is the dominant failure mode of the twin steel box girder bridges after a full-depth fracture of one girder, and the bridge could carry the dead load and 4.4 times HS 20 design truck before the collapse.Box Girder Bridges (Second edition) D C ILES MSc DIC ACGI CEng MICE Published by: The Steel Construction Institute Silwood Park Ascot Berkshire SL5 7QN Tel: 01344 623345 Fax: 01344 622944 . P:\CMP\Cmp657\pubs\P140\P140V02.doc ii Printed 16/02/04 1994, 2004 The Steel Construction InstituteSteel box bridge girders generally exhibit both aesthetic appeal and structural efficiency [1].Designed with single-cell or multi-cell cross-sections, steel box bridge girders have the advantages of being lightweight, possessing high torsional stiffness, and allowing for rapid erection [2].As a result, they have been widely utilized in the design of highway interchanges .Box Girder Bridge is the bridge consisting of steel box components that is assembled with bolts. Box Girder Bridge is planned with width of vehicle’s floor and pedestrian as it needs. The span for this bridge consists of two types, those are Standard Span ranging from 30 Meters to 60 Meters and Long Span ranging from 60 Meters to 200 Meters.
The failure of four steel box girder bridges during construction caused quite a furore. The use of such girders in bridge construction had been a fairly recent phenomenon, partly because the mathematical analysis was quite daunting before the advent of electronic computers. Their popularity came at a time when the post-war surge in bridge .The Proposed Design Specifications for Steel Box Girder Bridges as contained in Report No. FHWA-TS-80-205 are evaluated. The results of comparative designs done using the AASHTO code and the proposed specification are summarized. The differences in the designs are explained with reference to the differing design requirements of the two .The steel box girder bridge, because of its structural efficiency and aesthetics, has become increasingly popular as a bridge type. Because of four unfortunate erection accidents of box girder bridges in Austria, the United Kingdom, Australia, and Germany, this type of structure has received much recent attention. However, because of this attention, the behavior of steel box .

Bridges often improve the visual appeal of urban landscapes by incorporating curve elements to create iconic forms. However, it is noteworthy that curved bridges have unique mechanical properties under loads compared to straight bridges. This study analyzes a spatial three-curved steel box girder bridge based on an actual engineering case with a complex .Box girder bridges No. 1.08 SCI P185 Guidance notes on best practice in steel bridge construction 1.08/1 GN107R3.doc Revision 3 Scope This Guidance Note gives an overview of the main design issues for steel box girders in short and medium span bridge schemes. SCI-publication P140 (Ref 1) gives a more exten-sive treatment of steel box girder design. The impact of seven three-span continuous single box girder bridges, with overall span lengths ranging from 76.2 to 213.36 m (250–700 ft), due to vehicles moving across rough bridge decks is analyzed. The box girder is divided into a number of thin-walled beam elements. Both warping torsion and distortion are considered in the study.
Steel box girder redesign of a two-span bridge resulting in large construction cost savings for the client. "The use of LUSAS helped us meet our design deadline and to prove an alternative bridge design that will ultimately save the client a great deal of money in construction costs."Consist of two steel box girders Composite with a concrete deck.

Highlights New type of bridge, steel box girders partly stiffened by CFT arch ribs, is proposed. Girder bending moment decreases with arch span but does not depend on arch rise. Large deformation elastic–plastic analysis was carried out. It shows that initial imperfection decreases lateral torsional buckling strength. Estimated construction cost of CFT arch girder is . In the work of Ref. [13], a cable-stayed bridge with steel box girders and concrete bridge towers was adopted for finite element analysis based on temperature data, and both calculated results and measured data demonstrated that thermal load induced displacement of the main girder and bridge tower could be huge and may lead to cracks.

If your custom sheet metal parts need to be strong and/or waterproof, welding is also the way to go. Parts requiring a high degree of structural integrity, such as frames, should be welded rather than riveted since welding creates a more durable seam.
