BEHAVIOR OF A PRESTRESSED CONCRETE I-BEAM BRIDGE- BARTONSVILLE BRIDGE

THE FIELD TESTING OF AN EXISTING BEAM-SLAB HIGHWAY BRIDGE CONSTRUCTED WITH PRESTRESSED CONCRETE I-BEAMS AS THE MAIN LONGITUDINAL GIRDERS IS DESCRIBED. THE MAXIMUM MOMENT CROSS- SECTION (NEAR MIDSPAN), AND A CROSS-SECTION NEAR QUARTER- SPAN, WERE SELECTED AS THE TEST SECTIONS. THE PRINCIPAL OBJECTIVES WERE: (1) TO EVALUATE THE LATERAL DISTRIBUTION OF LIVE LOAD, AND (2) TO ESTABLISH THE AMPLIFICATION CHARACTERISTICS OF CRAWL RUN RESPONSE UNDER DYNAMIC AND CONTROLLED IMPACT LOADING. IT WAS FOUND THAT THE EXPERIMENTAL DISTRIBUTION FACTORS FOR THE INTERIOR GIRDERS WERE NEAR THE DESIGN VALUE, AS SPECIFIED IN THE PENNDOT BRIDGE DIVISION STANDARDS, AND IN THE AASHO SPECIFICATIONS. FOR THE EXTERIOR GIRDERS, THE EXPERIMENTAL VALUES WERE GREATER THAN THE DESIGN VALUES. /AUTHOR/
