Development of P-Y curves for single piles based on full-scale lateral load tests and the cone penetration test (CPT) in clayey soils

Journal of Materials and Engineering Structures
It is nowadays recognized that the load-transfer P-Y curves methods offer a powerful framework of analysis of the pile response under lateral loading.

x-y duality in topological recursion for exponential variables via quantum dilogarithm

SciPost Physics
For a given spectral curve, the theory of topological recursion generates two different families $\omega_{g,n}$ and $\omega_{g,n}^\vee$ of multi-differentials, which are for algebraic spectral curves related via the universal $x-y$ duality formula.

A note on certain integrals along polynomial compound curves

Journal of Inequalities and Applications, 2019
In this paper we consider a singular integral operator and a parametric Marcinkiewicz integral operator with rough kernel. These operators have singularity along sets of the form curves {x=P(φ(|y|))y′} $\{x=P(\varphi (|y|))y'\}$, where P is a real ...

Winkler springs (p-y curves) for liquefied soil from element tests

, 2014
In practice, piles are most often modelled as "Beams on Non-Linear Winkler Foundation" (also known as “p-y spring” approach) where the soil is idealised as p-y springs. These p-y springs are obtained through semi-empirical approach using element test results of the soil.

Statistical Evaluation of API P-Y Curve Model for Offshore Piles in Cohesionless Soils

Modelling
Pile foundations are widely used to support offshore wind turbines. While the p-y curve method is adopted for analysis of pile–soil interactions in popular design specifications, including the American Petroleum Institute (API), its accuracy remains ...

On the projective normality of Artin-Schreier curves

Le Matematiche, 2013
In this paper we study the projective normality of certain Artin-Schreier curves Y_f defined over a field F of characteristic p by the equations y^q+y=f(x), q being a power of p and f in F[x] being a polynomial in x of degree m, with (m,p)=1.

Effect of Slope on P-Y Curves Due to Surcharge Load

Soils and Foundations, 2008
An extensive program of laboratory model tests was undertaken to study the effect of slope on p-y curves due to surcharge load in dry sand. The paper concerns the method developed in a series of laboratory model tests to experimentally determine p-y curves.

Response of Monopiles Under Lateral Loading By Centrifuge Modeling

نشریه مهندسی دریا, 2016
One of the most common methods to analyze and design monopiles under lateral load is load-displacement curves, particularly the p-y curves, at different locations of the structure.

Parametric Investigation of p-y Curves for Improving the Design of Large Diameter Monopiles for Offshore Renewable Energy Applications

Applied Sciences
This study establishes a direct and quantitative link between field-scale monopile behavior, three-dimensional finite element (FE) modeling, and practical p-y curve formulations for large-diameter offshore monopiles.
