Paper Title:
Comparative Experimental Study on Flexural Property of Reinforced and Conventional PHC Pile
  Abstract

Reinforced PHC piles make use of nonprestressed steel bars to reinforce the initial steel cage, with the intent being to invent novel piles that have better flexural properties than the conventional PHC piles. In this study, a comprehensive test program was carried out with 12 full-scale test piles to compare the flexural properties of two different types of PHC piles. The flexural stiffness of the reinforced PHC pile is greater than the flexural stiffness of the conventional PHC pile. The Reinforced PHC pile and the conventional PHC pile exhibited similar axial stress development, planar section remained in pile mid-span during the initial period and the neutral axis shifted upward after concrete cracking. The cracking patterns and failure modes for two different types of PHC piles are evidently different. The moment capacities for reinforced piles were significantly higher than the values for the conventional piles, and the improvements increase in order from the pile specification of B to the AB to the A.
