This paper introduces a new type of prestressed uplift pile that adopts the semi-bonded composite anchor as main reinforcement. An in-situ experimental study was carried out to investigate pile’s deformation, stress, bearing capacity, and cracking characteristics, which were then compared with conventional piles. Results show although reinforcement ratio is only 0.75%, much less than (i.e., 3.8...

A Shallow foundation on cohesionless soil cannot support greater weights; piled raft foundations are recommended because they combine the load-bearing qualities of piles and raft. Combined Piled Raft Foundations (CRPF) efficient for tall buildings account both vertical lateral loads. In a pile foundation, raft’s load-resistance is disregarded due to soil-structure interaction. Simplification ma...

Florida Department of Transportation (FDOT) sponsored research performed at the University of Florida resulted in developing a wireless monitoring and real time static capacity estimate technology for driven piles. This new technology, Embedded Data Collector (EDC), uses two levels of instrumentation, embedded in the body of precast prestressed concrete piles near the head and tip. Strain and a...
