FATIGUE TESTS OF LARGE-SIZE WELDED PLATE GIRDERS

THIS REPORT DESCRIBES THE FATIGUE TESTS OF NINE LARGE-SIZE , WELDED PLATE GIRDERS. THE PURPOSE OF THE TESTS WAS TO EXAMINE THE FATIGUE BEHAVIOR OF THIN-WEB GIRDERS, PARTICULARLY THE WEBS, FOR THE FORMULATION OF DESIGN RECOMMENDATIONS. THE GIRDERS WERE SUBJECTED TO LOADING CONDITIONS OF HIGH SHEAR, PURE BENDING, AND THEIR COMBINATION. MAXIMUM APPLIED LOADS WERE AT A LEVEL COMPARABLE TO PRACTICAL MAGNITUDES. THREE FAILURE MODES EXISTED, CORRESPONDING TO THE THREE LOADING CONDITIONS. THE WEB MEMBRANE STRESSES WERE FOUND TO BE AGREEABLE WITH THE PREDICTIONS OF THE BEAM THEORY. ALONG THE FLANGES, THE SECONDARY BENDING STRESSES IN THE THIN WEBS CORRELATED WELL WITH THE LOCATIONS AND THE NUMBER OF CYCLES AT THE FIRST OBSERVATION OF THE CRACKS. /AUTHOR/
