FIELD TESTING OF AN ORTHOTROPIC STEEL DECK BRIDGE

FIELD STUDIES WERE MADE OF AN ORTHOTROPIC STEEL DECK BRIDGE TO INVESTIGATE: (1) CORRELATIONS BETWEEN OBSERVED STRUCTURAL BEHAVIOR AND THAT PREDICTED BY THEORETICAL ANANLYSES, EITHER EXISTING OR DERIVED IN THE COURSE OF THE PROJECT, (2) CONSTRUCTION AND FABRICATION PROBLEMS, AND (3) DURABILITY OF TWO TYPES OF WEARING SURFACES AND VARIOUS METHODS OF APPLICATION. THE NATURE OF THE STRUCTURE, THE LARGE NUMBER OF TRANSDUCER CIRCUITS (OVER 1,200), AND THE REQUIREMENT FOR EXPEDITIOUS ACQUISITION OF DATA REQUIRED SOME UNIQUE LOADING METHODS AS WELL AS SOPHISTICATED MACHINERY FOR TRANSDUCER READING AND DATA REDUCTION, TABULATION, AND PLOTTING. EQUIPMENT WAS CONSTRUCTED TO APPLY LARGE, SINGLE OR MULTIPLE, CONCENTRATED LOADS TO THE STEEL DECK. DATA REDUCTION AND PLOTTING METHODS WERE DEVELOPED. COST OF THE STRUCTURE WAS VERY HIGH, AS MIGHT BE EXPECTED IN THE SHORT-SPAN RANGE EMPLOYED. MOREOVER, IT HAS DEMONSTRATED A PARTICULAR VULNERABILITY TO ICING. /AUTHOR/
