THE ANALYSIS OF CURVED ORTHOTROPIC HIGHWAY BRIDGES BY THE FINITE DIFFERENCE TECHNIQUE

A FINITE DIFFERENCE SOLUTION IS PRESENTED FOR THE ANALYSIS OF CURVED ORTHOTROPIC PLATE AND CURVED GIRDER BRIDGES. THE EQUATIONS WHICH DETERMINE THE BRIDGE MOMENTS, DEFLECTIONS AND TORQUES ARE WRITTEN IN FORTRAN LANGUAGE FOR THE IBM 7094 AND IBM 1620 COMPUTERS. THIS METHOD OF ANALYSIS INCORPORATES INTERACTION OF ALL CURVED GIRDERS OF THE FLOOR SYSTEM AND THE SLAB IN EVALUATING ACTUAL STRESSES UNDER STATIC LOADS. BY CONSIDERING THE SLAB TO BE ORTHOTROPIC, THE METHOD ENCOMPASSES ANY TYPE OF DECK CONFIGURATION OR STIFFNESS IN A BRIDGE DESIGN OR ANALYSIS. THE ORTHOTROPIC PLATE EQUATIONS ARE DERIVED AND THE FINITE DIFFERENCE METHOD APPLIED FOR PARTICULAR BOUNDARY CONDITIONS. AN EXAMPLE IS PRESENTED WHICH ILLUSTRATES THE METHOD OF ANALYSIS. /BPR/
