THE COMPUTER ANALYSIS OF ORTHOTROPIC STEEL PLATE SUPERSTRUCTURES FOR HIGHWAY BRIDGES

A COMPUTER ANALYSIS WAS CONDUCTED OF FOUR ORTHOTROPIC PLATE BRIDGE DECK DESIGNS USING STEEL PLATE SUPERSTRUCTURES FOR HIGHWAY BRIDGES AND OF CONVENTIONAL CONSTRUCTION BRIDGE SPAN DESIGNS. COST COMPARISONS FOR THE BRIDGE DESIGNS SHOWS THAT FOR MODERN SHORT SPAN HIGHWAY BRIDGES, THE INTRODUCTION OF ORTHOTROPIC PLATE DESIGN OF THE SUPERSTRUCTURE CAN BE MORE ECONOMICAL ABOVE 130 FEET SPAN LENGTH THAN THE CONVENTIONAL BRIDGE DESIGN. ADDITIONAL SAVING MIGHT ACCRUE IN FAVOR OF THE ORTHOTROPIC BRIDGES BY USING LESS EXPENSIVE SUB-STRUCTURES, SAVING BY LESSER MAINTENANCE FOR STEEL DECKS, AND STANDARDIZING DETAILS TO FABRICATING PROCEDURES. THE PELIKAN-ESSLINGER METHOD WAS USED FOR THE ANALYSIS OF THE ORTHOTROPIC PLATE BRIDGE DECK. THREE SETS OF COMPUTER PROGRAMS WERE PREPARED IN FORTRAN LANGUAGE TO ANALYZE' /1/ AN ORTHOTROPIC PLATE BRIDGE DECK ON TWIN I-SHAPE GIRDERS WHERE THE DECK SPAN CONSISTS OF CLOSED RIBS, FLOOR BEAMS AND PLATES, /2/ AN ORTHOTROPIC PLATE BRIDGE DECK ON TWIN BOX GIRDERS WITH CLOSED RIBS, FLOOR BEAMS, PLATES AND CANTILEVERS, AND /3/ AN ORTHOTROPIC PLATE BRIDGE DECK ON TWIN BOX GIRDERS WITH CLOSED RIBS, FLOOR BEAMS AND PLATES.
