ANALYSIS OF HORIZONTALLY CURVED BRIDGES

YEARS AGO, BRIDGES WERE LOCATED BY DETERMINING THE MOST CONVENIENT CROSSING SITE, WITH LITTLE REGARD FOR THE GENERAL ALIGNMENT OF THE ROADWAY. TODAY, BRIDGES MUST FIT THE ALIGNMENT THAT HAS BEEN PREDETERMINED BY MANY OTHER CONSIDERATIONS. CURVED GIRDERS PERMIT THE DESIGNER TO MAKE USE OF CONTINUOUS CONSTRUCTION AND ITS INHERENT ADVANTAGES IN SITUATIONS WHICH MIGHT OTHERWISE BE LIMITED TO SIMPLE SPANS. THE MAJOR ADVANTAGES OF CURVED GIRDERS ARE STRUCTURAL EFFICIENCY, APPEARANCE AND SIMPLICITY IN CERTAIN PHASES OF DESIGN, DETAILING, AND CONSTRUCTION. AFTER A SHORT DISCUSSION OF THE TYPES OF GIRDER FRAMING, WHETHER OPEN OR CLOSED AN APPROXIMATE METHOD OF ANALYSIS IS DEVELOPED. THE FORMULAS ARE EXPANDED AND SOLVED, THE RESULTS BEING ILLUSTRATED WITH DATA PREPARED BY THE NEW YORK DEPARTMENT OF TRANSPORTATION. /AUTHOR/
