AN ANALYTICAL STUDY OF EIGHT DIFFERENT TYPES OF HIGHWAY BRIDGE STRUCTURES

THE REPORT PRESENTS CALCULATED MOMENTS AND DEFLECTIONS FOR EIGHT HIGHWAY BRIDGES OF DIFFERENT TYPES. THE LIVE LOADING USED ON ALL BRIDGES IS THE BUREAU OF PUBLIC ROADS TEST TRUCK LOADED TO APPROXIMATE AN H20-S16, AASHO DESIGN LOADING. THE BRIDGES ARE TREATED AS ORTHOTROPIC PLATES. TWO METHODS ARE USED TO SOLVE THE PLATE EQUATION, A SLOPE-DEFLECTION METHOD, AND A FINITE DIFFERENCE METHOD. RESULTS FROM THE TWO METHODS COMPARE WELL FOR EACH BRIDGE. SOME COMPARISONS ARE MADE BETWEEN RESULTS OBTAINED FROM DESIGN VALUES BASED ON THE 1961 AASHO BRIDGE SPECIFICATIONS AND THE CALCULATED VALUES. STRESSES AND DEFLECTIONS BASED ON SPECIFICATIONS WERE ALWAYS HIGHER THAN THOSE OBTAINED FROM THE ANALYTICAL SOLUTIONS. APPENDIXES TO THE REPORT CONTAIN SEVERAL COMPUTER PROGRAMS WHICH WERE USED IN THE ANALYTICAL SOLUTIONS. /BPR/
