Study on the Flexural Performance of Prestressed High ...

2018-7-17 Four prestressed high strength concrete (PHC) piles under low-cycle loading and two piles under monotonic flexural loading were tested to study the test phenomena, failure modes, hysteretic performance, ductility and bearing capacity. It was indicated that PHC piles failed suddenly and the bearing capacity decreased because of the tensile rupturing of prestressing tendons from the results,

Prestressed concrete pavements are an alternative to con ventional concrete pavements. Prestressing the pavement provides two primary advantages, conservation of materials and greatly expanded joint spacing. Between 1971 and 1979, four full-scale experimental prestressed concrete pavements were constructed across the United States (1).
