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...

This study presents the results from centrifuge modeling experiments performed to understand effects of temperature changes on vertical pullout capacity scale-model torpedo piles embedded in soft clay layers. The model pile is a pointed stainless-steel cylinder with fins at top, installed by self-weight base layer using stepper motor. An internal electrical resistance heater was used control te...

A finite element model has been developed to simulate nonlinear response of piles/drilled piers under axial loading. The nonlinear stress-strain behaviors of soils are modeled via Drucker-Prager and von Mises type plasticity. A parametric study is carried out to address the influence of various factors, such as soil friction approximation, dilatancy, effect of interface element and shear streng...

Design of foundations in earthquake prone areas needs special considerations. Shallow foundations may experience a reduction in bearing capacity and increase in settlement and tilt due to seismic loading. The reduction in bearing capacity depends on the nature and type of soil and ground acceleration parameters. In the case of piles, the soil-pile behavior under earthquake loading is generally ...

Pile foundations are used to support both vertical and horizontal loads in many geotechnical projects, such as coastal offshore engineering. In this project, the Finite Difference Method is proposed solve differential equation governing lateral axial pile response. Initially, behaviour of subjected load will be analysed. The effect various parameters like head fixity, cohesion surrounding soil,...

Abstract Bidirectional static load tests to evaluate the axial load-bearing capacity of large cross-sectional bored piles are indispensable. Nonetheless, this test is complicated, costly, and easy fail. A case history a bidirectional conducted in HoChiMinh City reported analyzed. In particular, pile with 1.8m diameter ∼60m embedment length, located Tan Binh district, City, tested using test. Th...

Approximately 75% of installed offshore wind turbines (OWTs) are supported by monopiles, a foundation whose design is dominated by lateral loading. Monopiles are typically designed using the p-y method which models soil-pile resistance using decoupled, nonlinear elastic Winkler springs. Because cyclic soil behavior is difficult to predict, the cyclic py method accounts for cyclic soil-pile inte...
