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.

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 ...

Analysis of Box Girders with Diaphragms
Journal of the Structural Division, 1968Analyses 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, 1985Simple 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

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.

Proportioning of Box Girder Bridges
Journal of the Structural Division, 1980The 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.

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 ...

<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.

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 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.
