OVERLOAD CAPACITY-PRESTRESSED COMPARED WITH REINFORCED CONCRETE

A QUESTION IS ASKED CONCERNING THE ECONOMY OF USING PRESTRESSED CONCRETE, IF CHEAPER IN A PARTICULAR CASE, INSTEAD OF USING REINFORCED CONCRETE HAVING A GREATER OVERLOAD CAPACITY. COMPARISON IS MADE OF THE OVERLOAD CAPACITIES OF SIMPLE SPAN BRIDGE GIRDERS IN BOTH PRESTRESSED AND REINFORCED CONCRETE. ULTIMATE STRENGTH CALCULATIONS ARE BASED ON THE PLASTIC THEORY FOR BOTH TYPES OF CONSTRUCTION. REFERENCES ARE GIVEN TO SUPPORT FORMULAS USED TO CALCULATE ULTIMATE STRENGTHS. IN MOST CASES, THE GIRDERS COMPARED ARE FOUND IN BRIDGES DESIGNED AND BUILT BY THE CALIFORNIA DIVISION OF HIGHWAYS. THREE RANGES OF SPAN LENGTHS ARE CONSIDERED:-UNDER 60 FEET, 60-80 FEET, AND 80-120 FEET. /AUTHOR/
