ANALYSIS AND DESIGN OF CURVED BOX GIRDER BRIDGES

THE MAIN GEOMETRIC PARAMETERS OF CURVED BRIDGES PRESCRIBED BY HIGHWAY ENGINEERING REQUIREMENTS ARE STUDIED. THE EXISTING APPROXIMATE METHODS OF ANALYSIS ARE REVIEWED AND TWO NEW REFINED METHODS DEVELOPED. THE FIRST ONE, BASED ON THE FINITE ELEMENT METHOD FOR WHICH A GENERAL COMPUTER PROGRAM WAS WRITTEN, IS USED TO ANALYZE GENERAL NON-PRISMATIC FOLDED PLATE STRUCTURES WITH AN INCORPORATED THREE-DIMENSIONAL FRAME. THE SECOND APPROACH IS THE FINITE STRIP METHOD OF ANALYSIS APPLIED TO FOLDED PLATE STRUCTURES CURVED IN PLAN, FOR WHICH A COMPUTER PROGRAM HAS BEEN WRITTEN ALSO. THIS METHOD IS RESTRICTED TO STRUCTURES SIMPLY SUPPORTED ALONG THEIR STRAIGHT RADIAL EDGES, BUT THE EXTENSION OF THE THEORY TO INCLUDE INTERIOR SUPPORTS IS ALSO DISCUSSED. THE BEHAVIOR OF CURVED BOX GIRDER BRIDGES IS STUDIED ON THE BASIS OF THESE METHODS. WHEEL LOAD DISTRIBUTION CHARACTERISTICS ARE INVESTIGATED WITH RESPECT TO HOW THEY CHANGE WITH THE MAJOR BRIDGE PARAMETERS. DESIGN RECOMMENDATIONS FOR COMBINING EFFICIENCY AND ACCURACY OF THE DESIGN OF CURVED BOX GIRDER BRIDGES ARE PRESENTED. /AUTHOR/
