STRUCTURAL BEHAVIOR OF THE SOUTH ROAD CURVED GIRDER BRIDGE

THE FIELD TESTING OF A HORIZONTALLY CURVED STEEL GIRDER BRIDGE OF WELDED I-GIRDER AND CONCRETE SLAB CONSTRUCTION IS DESCRIBED; AND THE SUBSEQUENT ANALYSES MADE TO DETERMINE THE ANALYTICAL STRESSES AND DEFORMATIONS WHICH WOULD MATCH THOSE PRODUCED BY THE CONSTRUCTION AND TEST VEHICLE STATIC LOADINGS. FOR THE CONSTRUCTION LOADING, SLAB LOAD DATA WERE SELECTED FOR COMPARISON WITH ANALYTICAL DATA PRODUCED BY THE "APPROXIMATE" AND CURVED GRID METHODS WITH VARIATIONS IN THE STIFFNESS PARAMETERS OF MOMENTS OF INERTIA AND TORSIONAL CONSTANTS. FOR THE LIVE LOADING, AN FHWA TEST VEHICLE, WHICH CLOSELY APPROXIMATED AN HS 20 TRUCK, WAS DRIVEN ACROSS THE STRUCTURE ALONG FIVE DIFFERENT LANES. THE MEASURED STATIC RESPONSE OF THE STRUCTURE IS COMPARED WITH THE PREDICTED RESPONSE. GENERAL ASPECTS OF STRUCTURAL BEHAVIOR ARE DISCUSSED AND CONCLUSIONS DRAWN ABOUT THE BEHAVIOR AND THE ANALYTICAL METHODS USED. /FHWA/
