ANALYTICAL AND EXPERIMENTAL BEHAVIOR OF A SIMPLE-SPAN GIRDER BRIDGE
THE BEHAVIOR OF A SIMPLE-SPAN, COMPOSITE GIRDER BRIDGE IS PREDICTED BY THE FINITE-DIFFERENCE METHOD AS USED IN THE SOLUTION OF CONTINUOUS ORTHOTROPIC PLATES ON FLEXIBLE SUPPORTS. THIS METHOD INCORPORATES THE USE OF SEVERAL COMPUTER PROGRAMS. SEVERAL MODIFICATIONS TO THE GIRDER STIFFNESSES AND EFFECTS OF THE PARAPETS ARE EXAMINED, AND EQUIVALENT ORTHOTROPIC PLATE PARAMETERS ARE STUDIED. IN ADDITION TO THE ANALYTICAL STUDY, EXHAUSTIVE FIELD TESTS WERE CONDUCTED ON THE BRIDGE. MANY LONGITUDINAL AND TRANSVERSE TRUCK POSITIONS, IN WHICH THE U. S. BUREAU OF PUBLIC ROADS TEST VEHICLE APPLIED THE STATIC LOAD, WERE USED AND THE EFFECTS WERE RECORDED. THE BRIDGE WAS FULLY INSTRUMENTED WITH BOTH STRAIN AND DEFLECTION GAGES. COMPARISONS MADE BETWEEN THE ANALYTICAL AND EXPERIMENTAL GIRDER STRAINS AND DEFLECTIONS RESULT IN GOOD AGREEMENT. /AUTHOR/
