Title: LIVE LOAD DISTRIBUTION ON SIMPLE SPAN STEEL I-BEAM COMPOSITE HIGHWAY BRIDGES AT ULTIMATE LOAD
Abstract: THE PURPOSE OF THIS RESEARCH WORK IS TO ESTABLISH A MORE REALISTIC LATERAL LOAD DISTRIBUTION FACTOR, IN CONJUNCTION WITH THE AASHO LOAD FACTOR DESIGN METHOD. AT PRESENT THIS TECHNIQUE UTILIZES THE ELASTIC DISTRIBUTION CRITERIA, WHICH IS NOT CONSISTENT WITH THE PHILOSOPHY OF THE LOAD FACTOR TECHNIQUE. THE DISTRIBUTION FACTOR, AT ULTIMATE LOAD AND DESIGNATED AS THE PLASTIC DISTRIBUTION FACTOR (DP) IS: DP = 3.45 - 1.809 GAMMA + 0.315 SQ GAMMA, WHERE GAMMA = NO. OF GIRDERS/NO. OF LANES. THE PARAMETERS OF THE BRIDGES ARE: 6' TO 9' GIRDER SPACING, 4 TO 9 GIRDERS, AND 2 TO 4 LANES.
