FINITE ELEMENT ANALYSIS OF SKEW COMPOSITE GIRDER BRIDGES

THE ANALYTICAL DEVELOPMENT OF A FINITE ELEMENT METHOD USING A DISPLACEMENT MODEL FOR ANALYZING THE BEHAVIOR OF LINEAR ELASTIC SKEW COMPOSITE GIRDER AND SLAB BRIDGES IS DISCUSSED. TWO COMPUTER PROGRAMS WHICH ARE CAPABLE OF DETERMINING DISPLACEMENTS AND INTERNAL FORCES IN THE BEAMS AND SLAB ARE LISTED. LINEAR ELASTICITY AND SMALL DEFORMATION THEORY ARE ASSUMED. THE ANALYTICAL RESULTS AGREED CLOSELY WITH DEFLECTIONS OF SMALL PLASTIC MODELS SUBJECTED TO STATIC LOADS. IT IS CONCLUDED THAT THE FINITE ELEMENT METHOD USING THE DISPLACEMENT MODEL IS WELL ADAPTED TO ANALYZE ELASTIC SKEW COMPOSITE PLATES. THE METHOD PERMITS RAPID SOLUTION OF SUCH STRUCTURES, WITH VARYING ANGLES OF SKEW, BEAM GEOMETRY, BOUNDARY CONDITION AND LOADING. /BPR/
