Abstract
An octagonal Ultra-High Performance Concrete prestressed pile system for deep foundation applications utilizes an octagonal cross-sectional geometry with 30-inch flat-to-flat external diameter and central void of 26-32 inches diameter optimized for material efficiency and structural performance. The system employs Ultra-High Performance Concrete with compressive strength exceeding 18,000 pounds per square inch and conventional carbon-steel prestressing strands to provide structural capacity equivalent to steel pile systems. The octagonal geometry with central void targets approximately one cubic yard of UHPC per fifty feet of pile length, enabling direct economic comparison with steel alternatives while providing enhanced durability and reduced dead weight by up to 75%. The system includes modular splice connections for extended length capability and addresses multiple market sectors including high-rise buildings, bridges, industrial facilities, and general infrastructure projects. The octagonal configuration with central void provides superior material utilization compared to conventional square and circular pile geometries while maintaining excellent driving characteristics and structural performance.
