<p>The box girder is today the most widely used superstructure in cocnrete bridge construction. The aim of this document is to relieve the engineer of the study of today's hardly surveyable mass of literature on the subject so that he can better devote that time to the actual design of the bridge.

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.

Journal of Structural Engineering, 1988
Based on the curvilinear coordinate system, the spline finite strip method is extended to the elasto-static analysis of circular and noncircular box-girder bridges. As the curvature effect cannot be ignored, the webs of the bridges have to be treated as thin shells and the flanges as flat curved plates.

The Case for the Semi-Box Girder
Engineering Journal, 1972The semi-box girder is that breed having a partly open and a partly closed cross section. As such, it is not as torsionally stiff as a rectangular box girder, but substantially stiffer in this regard than an open section. Its main attribute is its ability to resist failure by lateral torsional buckling and, as such, is useful in bridge work to ...

Thermal behaviour of composite box-girder bridges
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2000This paper investigates the behaviour of composite box-girder bridges subject to environmental thermal effects such as solar radiation, air temperature and wind speed. It is based on the statistical analysis of measured temperature data which were recorded hourly in a newly constructed composite box-girder bridge for about 20 months continuously ...

Curved Steel Box-Girder Bridges: A Survey
Journal of the Structural Division, 1978A summary of responses to a questionnaire sent to bridge designers and owners in the United States, Great Britain, Europe, Japan, and Canada is presented. Features of the response include overall geometry of the structures, such as radii and span lengths.

This paper discusses the coordinated design research program conducted under the sponsorship of the United States Steel Corporation, on the subject of steel box girder bridges. The assigned objective of this investigation was the development of design theory, methods and specifications for steel box girder bridges of short to medium span lengths ...

Shear Lag in Box Girder Bridges
Journal of Bridge Engineering, 2002A finite-segment method for analyzing shear-lag effects in box girders is presented in this paper, with an assumption that the spanwise displacements of the flange plates are described by a third-power parabolic function. The governing differential equations for two generalized displacements are established according to the principle of minimum ...

The loadbearing capacity of box girders
Batiment International, Building Research and Practice, 1980Although admittedly based on research which is modest compared to expenditure on the subject in other countries, these observations by Professor Bergfelt, of Chalmers University, Gothenburg, are arresting. They suggest that those assumed strength reserves in steel box girder design which are called upon during the construction operations may be ...

Design and Analysis of a Prestressed Concrete Box Girder
1994New codes for the design of concrete structures in The Netherlands give designers the opportunity to utilize the possibilities of partial prestressed concrete. It will be possible in bridge construction to combine prestressing and reinforcement so that the result will be optimal; technically and economically.
