Abstract: This study explores the behavior and stress development in prestressed high-strength concrete (PHC)–steel composite pile foundations subjected to static load testing. A field investigation was conducted to evaluate the load transfer mechanisms, stress distribution, and deformation characteristics under varying static load conditions. PHC–steel composite piles, owing to their combined properties of high compressive strength and ductility, were analyzed for their load-bearing performance and structural stability. The study employed advanced instrumentation, including strain gauges and load cells, to measure stress and deformation patterns in real time. Results revealed significant stress concentration near the pile-soil interface and differential stress development along the pile length. The findings are compared with previous studies, contributing to the understanding of composite pile behavior and offering recommendations for optimizing foundation design.
