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 ...

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 ...

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.

Analysis of Box Girders with Diaphragms

Journal of the Structural Division, 1968
Analyses based on thin-walled beam theory are presented for multicell box girders of deformable cross section. The influence of flexible interior diaphragms on stresses arising from deformation of the cross section is investigated for torsional loadings and box-cell properties appropriate for steel and reinforced concrete highway bridges.

Approximations for Moments in Box Girders

Journal of Structural Engineering, 1985
Simple design approximations are presented for determining the transverse moments in single‐span, single‐cell concrete box girder bridges. Five representative loading cases are considered which can be used in combination to model a range of vertical dead and live loading and wind loading. The design approximations are based on the analysis of the cross

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.

Box girders

Chapter 5 discusses the behavior and design of box-girder bridges under traffic loads. First, the response of a rectilinear, closed, hollow-section girder is examined under the action of an eccentrically applied traffic load. The girder is considered to have a deformable profile, which means that the theory from the previous chapter cannot be applied ...

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.

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.

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.
