PRESTRESSED COMPOSITE STEEL BEAM DESIGN

FOUR DECK-GIRDER HIGHWAY BRIDGES, LOCATED IN AN AREA WHICH HAS SINCE BEEN FLOODED AS A PART OF A TVA RESERVOIR, WERE TESTED TO FAILURE UNDER STATIC LOADING. A SYSTEM OF ROCK ANCHORS WAS USED TO DEVELOP THE NECESSARY FORCES. THE LOADS WERE APPLIED TO A BRIDGE SPAN AT EIGHT LOAD POINTS, SIMULATING THE REAR WHEELS OF TWO AASHO HS TRUCKS, ONE TRUCK IN EACH TRAFFIC LANE. ALL OF THE BRIDGES BUT ONE FAILED, AS EXPECTED, IN A FLEXURAL MODE. COMPOSITE ACTION WAS LOST IN THE PRESTRESSED CONCRETE BRIDGE, AND THE TWO INTERIOR GIRDERS FAILED IN SHEAR. THE FAILURE LOAD FOR EACH BRIDGE, ACHIEVED AT THE EXPENSE OF LARGE DEFLECTIONS, WAS SEVERAL TIMES THE DESIGN LOAD FOR THE BRIDGE.
