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.

Effect of encased concrete on section temperature gradient of corrugated steel web box girder
, 2021Thirty-two temperature sensors, a solar radiation sensor, wind speed, and direction sensor were installed on the bridge for the field monitoring of structural temperature, solar radiation, and wind. The frequency was set at 60 min for 211 days. Empirical

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.

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 ...

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.
