MODEL AND PROTOTYPE STUDIES OF BOX GIRDER BRIDGE

A FULL-SIZE, REINFORCED CONCRETE, BOX GIRDER BRIDGE WITH AN 80 FT SPAN, AND A QUARTER-SCALE MODEL OF THE SAME, WERE INSTRUMENTED AND TESTED. THIS PAPER PRESENTS MODEL TEST DATA, AUGMENTS THE SCOPE OF PROTOTYPE ANALYSES, AND ESTABLISHES THREE-WAY CORRELATIONS AMONG PROTOTYPE AND MODEL DATA AND THEORETICAL ANALYSES. ADDITIONAL STUDIES ARE MADE OF TRANSVERSE DISTRIBUTIONS OF LIVE LOAD RESISTING MOMENTS TO PROTOTYPE STRINGERS, INCLUDING EFFECTS OF AN INTERMEDIATE DIAPHRAGM AND BARRIER RAILINGS ON THOSE DISTRIBUTIONS. THREE-WAY CORRELATIONS OF RESISTING MOMENT DISTRIBUTIONS ARE VERY GOOD. THE THEORY EXAGGERATED SLIGHTLY THE INFLUENCE OF THE DIAPHRAGM BY ASSUMING IT TO BE RIGID. INFLUENCE OF THE BARRIER CURBS WAS ACCURATELY ASSESSED. THEORETICAL TRANSVERSE STRAIN DISTRIBUTIONS DID NOT ALWAYS AGREE WITN THOSE OBSERVED. /AUTHOR/
