BOX GIRDER MODEL STUDIES

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. THE TEST RESULTS ARE COMPARED WITH THE PREDICTIONS BASED ON THE "B.E.F. ANALOGY," A METHOD OF ANALYSIS WHICH ACCOUNTS FOR THE WARPING AND DISTORTION STRESSES. IT IS CONCLUDED THAT DEFORMATION OF A BOX GIRDER CROSS SECTION MAY CAUSE SUBSTANTIAL WARPING AND DISTORTION STRESSES, AND THAT THESE STRESSES CAN BE EFFECTIVELY CONTROLLED BY PRUDENT DIAPHRAGM PLACEMENT. /AUTHOR/
