Steel Box Girder Bridges

Engineering Journal, 1973
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.

Thermal behaviour of composite box-girder bridges

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2000
This 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 ...

Box Girder Bridge Design

Engineering Journal, 1967
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, 2002
A 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 Case for the Semi-Box Girder

Engineering Journal, 1972
The 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 ...

Box Girder Bridge Diaphragms with Openings

Journal of the Structural Division, 1979
The diaphragms considered in this study are of the type frequently met in box girder bridges supported on single slender piers. The outside loads are assumed to be transmitted from the bridge main girders to the inclined (or vertical) surfaces of the diaphragms in the form of uniform shearing forces.

The loadbearing capacity of box girders

Batiment International, Building Research and Practice, 1980
Although 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

1994
New 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.

Strength and Deformation of Pretensioned Box Girders

Journal of the Structural Division, 1981
An analytical computer model is developed to analyze prestressed concrete box girders subjected to torque, bending moment, and shear. Its performance is evaluated in comparison with results of experimentation and current theory. Emphasis is placed on the prediction of post-cracking member deformations in addition to ultimate member strength.

Overview of Precast Segmental Box Girder

2019
This chapter gives updates on the current work for segmental box girder (SBG) under static load test and the measurement to determine the elastic behavior, displacement, stress and strain of the SBG. Moreover, study on finite element analysis (FEA) and transversal slope on SBG is also highlighted in this chapter.
