Abstract:
WORK AT PURDUE UNIVERSITY IS BEING UNDERTAKEN TO INVESTIGATE THE ECONOMIC POSSIBILITIES OF NICKEL-COPPER HIGH-STRENGTH ALLOY STEELS IN SHORT-AND MEDIUM-LENGTH HIGHWAY BRIDGES. IN THE SECOND PHASE REPORTED HERE AN ANALYSIS WAS MADE OF THE COMPARATIVE ECONOMIC USE OF VARIOUS STEELS FOR WELDED I-SECTION STRINGERS WITH CONCRETE DECK FOR SHORT-AND MEDIUM-LENGTH HIGHWAY BRIDGES WITHIN THE FRAMEWORK OF THE STANDARD DESIGN SPECIFICATIONS. THE RESULTS INDICATE THAT STRUCTURES OF THIS TYPE MAY BE FABRICATED AND ERECTED USING A NICKEL-COPPER GRADE OF HIGH-STRENGTH LOW-ALLOY STEEL AT ABOUT THE SAME FIRST COST IN DOLLARS AS IF A373 STRUCTURAL STEEL WERE USED, PROVIDED ADEQUATE DIAPHRAGMS ARE USED IN ORDER THAT FULL LIVE LOAD AND IMPACT DEFLECTION MAY BE EQUALLY DISTRIBUTED TO ALL STRINGERS. /AUTHOR/
