The pile construction method is changing from the pile driving operation to the injected precast pile method. It is to prevent environmental damage and to minimize complaints caused by noise. Therefore, economic alternatives optimized for the injected precast pile method are required. In this study, the enhanced spun reinforced concrete piles manufactured by high strength materials were proposed. Experimental tests were conducted to evaluate their structural safety and nonlinear finite element analysis was performed to improve the reliability of experimental results. The experimental results and the analytical results were in good agreement with each other and the proposed enhanced spun reinforced concrete pile has better performance than that required by the design. However, the performance of the joint using the existing method used in the PHC pile was considered to be insufficient.
