P-y Curves of laterally loaded barrettes
Innovative Infrastructure Solutions, 2021Rectangular shaped piles (barrettes) are extensively used in construction projects to resist relatively high lateral loads in different onshore and offshore facilities. The need to analyze barrettes subjected to lateral loads is one of the challenges in the field of deep foundations. P-y curves and finite element method are widely trusted approaches to

Re-Examination Of P-Y Curve Formulations
Offshore Technology Conference, 1979ABSTRACT In the analysis of piles supporting offshore structures, the key element in predicting the response to lateral loads is the determination of the appropriate lateral load - deformation relationships (p-y curves) for the soil.

Cyclic P-Y Curves for a Pile in Cohesive Soil
Geotechnical Earthquake Engineering and Soil Dynamics IV, 2008A lateral load test was performed on a full-scale steel pipe pile installed in a soil profile consisting of cohesive, fine-grained soils with occasional sand layers. The pile was loaded in nine increments from 0 to 89 mm of displacement, with 15 loading cycles applied for each increment.

Determination of Multidirectional p-y Curves for Soft Clays
Geotechnical Testing Journal, 2005Abstract The evaluation of performance of soil-pile-structure systems under seismic loading is one of the most complex problems in earthquake engineering. In the most common methodology, force-displacement curves are used to describe the nonlinear response of discrete soil springs connecting the piles to the “free-field” soil column ...

Cyclic p-y Curves in Clays for Offshore Structures
Offshore Technology Conference, 2019Abstract Pile foundations supporting offshore structures are typically subjected to lateral cyclic loading. In design, the pile response under peak design load is generally estimated using a beam-column model where soil-structure interaction is simulated with a series of uncoupled non-linearly force-displacement springs (p-y curves ...

A method for p-y curve based on Vesic expansion theory
Soil Dynamics and Earthquake Engineering, 2020Abstract In the recent years, the construction of urban infrastructure projects has developed rapidly. When the structure systems of these major infrastructures are subjected to various horizontal loads during operation, it may cause permanent lateral deformation of the pile and instability and damage of the foundation soil.

Experimental Evaluation of p-y Curves Considering Development of Liquefaction
Journal of Geotechnical and Geoenvironmental Engineering, 2013AbstractAlthough evidence in the literature indicates that the lateral p-y resistance of piles in liquefiable soils is significantly reduced, the shape and amplitude of the reduced p-y curve during pore pressure buildup are needed for reliable design of pile foundations.

Development of p-y Curves for Partly Saturated Silts and Clays
New Technological and Design Developments in Deep Foundations, 2000Lateral load tests were performed on 20 drilled shafts, 200 mm and 230 mm in diameter, at five sites in Virginia, where the foundation soils consisted of partially saturated silts and clays with both cohesion and friction. Laboratory strength tests were performed on undisturbed samples of the soils, and the deflection measured in the field tests were ...

Slope effect on dynamic p–y backbone curve in dry sand
Soil Dynamics and Earthquake Engineering, 2021Abstract This study aims to evaluate the slope effect on the dynamic p–y backbone curve, which is a worldwide simplified tool in the seismic design of pile foundations. Data of dynamic centrifuge tests on single and group piles in sloping sandy ground were adopted to derive soil resistance and pile displacement.

P-Y curves for laterally loaded single piles: Numerical validation
Marine Georesources & Geotechnology, 2021Pile foundations are widely used in marine and coastal engineering structures. The correct analysis method must be used to ensure the safety of piled systems used in marine and coastal structures. Despite several methods available in the literature, the numerical method is increasingly applied for understanding the loading mechanism of pile-soil ...
