CONCRETE BOX-GIRDER BRIDGES AS SANDWICH PLATES

A RELATIVELY SIMPLE, ACCURATE METHOD FOR THE COMPLETE DETERMINATION OF INTERNAL MOMENTS, SHEARS, AND DEFLECTIONS IN CONCRETE BOX GIRDER BRIDGES WITH STATICALLY APPLIED EXTERNAL VERTICAL LOADS HAS BEEN DEVELOPED AND IS DESCRIBED. THE METHOD OF ANALYSIS USED IS BASED ON THE CONCEPT OF REPLACING THE ACTUAL STRUCTURE BY AN EQUIVALENT UNIFORM PLATE WHICH MODELS THE BEHAVIOR OF THE ACTUAL STRUCTURE. THE OBJECTIVES OF THE STUDY, WHICH ARE ANALYZED IN DETAIL, ARE A DISCUSSION OF THE BASIS AND APPLICABILITY OF THE ANALYSIS OF BOX GIRDER BRIDGES BY SANDWICH PLATE THEORY; PRESENTATION AND SOLUTION OF THE GOVERNING EQUATIONS FOR THE BOUNDARY CONDITIONS AND LOADINGS CONSIDERED; THE DEVELOPMENT OF PROCEDURES FOR COMPUTING GOVERNING STIFFNESS PARAMETERS; AND PRESENTATION OF RESULTS DERIVED FOR A SAMPLE STRUCTURE AND COMPARISON OF PREDICTED BEAM BENDING MOMENTS WITH CORRESPONDING QUANTITIES MEASURED IN A FULL SCALE FIELD TEST BRIDGE. /AUTHOR/
