THE BEHAVIOR OF A CURVED BOX BEAM MODEL BRIDGE

TESTING OF A SMALL PLEXIGLAS CURVED BOX BEAM MODEL BRIDGE IS DESCRIBED. THE MODEL CONSISTED OF A THREE CELL UNIT WITH A COMMON TOP PLATE ELEMENT. THE MODEL WAS TESTED AS A SINGLE SPAN AND A TWO-SPAN STRUCTURE. STRAIN, DEFLECTION, AND ROTATION MEASUREMENTS WERE TAKEN. A SERIES OF STIFFNESS MODELS WERE ALSO FABRICATED AND TESTED IN ORDER TO DETERMINE THE STIFFNESS PROPERTIES. THE RESULTING EXPERIMENTAL DATA WAS COMPARED WITH ANALYTICAL DATA. THE ANALYTICAL DATA WAS OBTAINED FROM A SERIES OF COMPUTER PROGRAMS INCORPORATING THE SLOPE DEFLECTION THEORY. IT IS CONCLUDED THAT THE SLOPE DEFLECTION METHOD PROVIDES A USEFUL TECHNIQUE IN THE ANALYSIS OF BOX BEAM MODELS. THE USE OF SINGLE BOX SECTION PROPERTIES, CONSIDERING ONLY BENDING AND ST. VENANT TORSIONAL PROPERTIES, PROVIDES GOOD RESULTS. /AUTHOR/
