For PHC pile, mechanical connection joints can be essential to connect PHC piles over 15m in length for deep foundation. This study was examined flexural capacity of PHC pile connected with high-performance connection device. To examine flexural capacity of PHC pile, two PHC piles with 5m length were connected using ring-type connecting plate developed recently. Its connection capacity and failure mode were evaluated through four-point flexure test.
