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 ...

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 ...

Analysis of RCC T-beam and prestressed concrete box girder bridges super structure under different span conditions

, 2020
A bridge is a structure that provides passage over an obstacle without closing the path below. The required crossing may be for a road, rail, pedestrian, canal, or pipe. For constructing the bridges has many types of sections among which Tee beam and Box

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.
