HIGH-STRENGTH STEEL AS REINFORCEMENT FOR CONCRETE BRIDGES: FINAL REPORT
Two experimental concrete bridge structures reinforced with high-yield-strength steel were designed and constructed in 1964 on arterial highways in Rochester, New York, and instrumented to determine their live-load and long-term dead-load performance. Eight years of deflection measurements and crack surveys are summarized and analyzed. Measured deflections are also compared with theoretical values. The test results indicate that the ACI Code 318-71 method, with Branson's suggested revisions, is adequate for prediction of total long-term dead-load detection, and that Yu and Winter's Method C, used in the design, significantly undestimates this deflection. It is concluded that drying shrinkage is a major contributor to time-dependent deflection of concrete bridge structures reinforced with high-strength steel. /FHWA/
