STATIC BENDING TESTS ON LONGITUDINALLY STIFFENED PLATE GIRDERS

THIS REPORT DESCRIBES STATIC BENDING TESTS OF FIVE LONGITUDINALLY STIFFENED PLATE GIRDERS. THE EXPERIMENTAL VARIABLES WERE THE PANEL SIZE AND THE LONGITUDINAL STIFFENER SIZE. THE PRIMARY TEST OBJECTIVES WERE' /1/ TO DETERMINE TO WHAT EXTENT LONGITUDINAL STIFFENERS CAN CONTRIBUTE TO THE RESISTANCE OF THE WEB TO VERTICAL BUCKLING OF THE COMPRESSION FLANGE, /2/ TO DETERMINE HOW THE STRESS REDISTRIBUTION AT LOADS ABOVE THE THEORETICAL WEB BUCKLING LOAD IS AFFECTED BY THE PRESENCE OF A LONGITUDINAL STIFFENER AND /3/ TO DETERMINE TO WHAT EXTENT LATERAL WEB DEFLECTIONS CAN BE REDUCED BY THE USE OF A LONGITUDINAL STIFFENER. THE TEST SETUP AND TEST PROCEDURE ARE DESCRIBED AND THE RESULTS ARE ANALYZED AND DISCUSSED. IT IS CONCLUDED THAT THE LONGITUDINAL STIFFENERS WERE EFFECTIVE IN RETARDING STRESS REDISTRIBUTION AND IN CONTROLLING WEB DEFLECTIONS, BUT FOR THE STIFFENER SIZES USED IN THESE TESTS, NO SIGNIFICANT INCREASE IN BENDING STRENGTH DUE TO THE PRESENCE OF LONGITUDINAL STIFFENERS WAS OBSERVED. /AUTHORS/
