Box-shaped girders

International Journal of Mechanical Sciences, 1975
Abstract The influence of rigidity and spacing of diaphragms on the deformation of a thin-walled one- to four-cell beam cross-section symmetrical about two axes was studied. The end cross-section of a simply supported beam subjected to antisymmetric loads applied mid-span of the beam keeps its shape and allows warping of the cross-section.

Innovative Box girder having Footpath at Bottom of Box girder by Cantilevering Soffit slab

IABSE Congress Reports, 2023
<p>Innovative structural forms for medium span bridges are a challenging effort for bridge design engineers especially in built-up area locations, where social impact plays a crucial role. Box girders are flexible forms compared to conventional ‘I’ girders, in the sense that they can have curved plan as well as varying shape of cross sections ...

Curved Box‐Girder Bridges

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.

Box Girder Model Studies

Journal of the Structural Division, 1969
AN EXPERIMENTAL STUDY OF THE STRESSES IN A BOX GIRDER SUBJECTED TO CONCENTRIC AND TORSIONAL LOADING CONFIGURATION IS DESCRIBED. TESTS WERE CONDUCTED ON A PLEXIGLAS MODEL TO EXAMINE THE EFFECTS OF INTERIOR DIAPHRAGMS IN REDUCING THE WARPING AND DISTORTION STRESSES CAUSED BY DEFORMATION OF THE CROSS SECTION.

Experiment on Box Type Girders

Transactions of the Japan Society of Mechanical Engineers, 1958
For the purpose of researching the strength and the rigidity etc. of box type girders used for overhead travelling cranes, full-sized model experiments were conducted. Two model girders were used. The top deck and two web plates of one model (girder 2) were reinforced by longitudinal stiffners, while those of the other (girder 1) were not.

Concrete Box-Girder Bridges

1982
<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.

Shear Lag in Box Girders

Journal of the Structural Division, 1981
An initial approximate method is presented to evaluate the shear lag phenomenon in reinforced concrete single-box girder bridges. Assuming an ideal cross-section and considering a symmetrical deformation of the top and bottom slabs, but preserving continuity conditions at the web-slab intersection points, a fourth order non-homogeneous differential ...

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 ...

Proportioning of Box Girder Bridges

Journal of the Structural Division, 1980
The selection of proper plate sized for box girder bridges, requires extensive trials and experience. Often this experience is not transferred to the engineering community because it is limited in that only several such bridges may have been designed.

Simplified analysis of FRP box-girders

Composite Structures, 2003
Box-girder analysis and design should take into consideration stresses due to longitudinal bending moment, shear force, torsion, distortion, shear-lag and transverse bending as well as instability of the flange under compression and web under shear as plates and stiffened panels.
