THE POSSIBILITIES IN BRIDGE CONSTRUCTION BY THE USE OF HIGH- ALLOY STEELS

THE USE OF HIGH-ALLOY STEELS IN CONSTRUCTION OF LONG-SPAN BRIDGES IS DISCUSSED BY ANALYSIS OF THE FOLLOWING: (1) THE WEIGHTS OF DIFFERENT SPAN LENGTHS FOR SIMPLE SPANS IN CANTILEVER BRIDGES USING STEELS OF VARIOUS ELASTIC LIMITS (2) INDICATION OF THE EXTREME PRACTICAL LIMITS OF SPAN LINGTHS OF CANTILEVER BRIDGES CONSTRUCTED OF SUCH STEELS, AND (3) THE ECONOMICS OF FINISHED BRIDGES USING STEELS OF VARIOUS ASSUMED ELASTIC LIMITS. THE ECONOMICAL ADVANTAGES OF ALLOY STEELS ARE STRESSED. IT IS SHOWN THAT THE POSSIBLE LIMITS OF MAIN SPAN LIFT FOR CANTILEVER BRIDGES VARY FROM 2,000 FEET FOR CARBON-STEEL STRUCTURES TO ABOUT 3,500 FEET FOR THOSE BUILT OF METAL HAVING AN ELASTIC LIMIT OF 100,000 PSI. DIAGRAMS ARE PRESENTED SHOWING A COMPARISON OF COSTS BETWEEN ANY ALL-CARBON-STEEL BRIDGE AND THE CORRESPONDING STRUCTURE BUILT CHIEFLY OF THE METAL TO WHICH THE DIAGRAMS PERTAIN.
