Development of p-y Curves of Laterally Loaded Piles in Cohesionless Soil [PDF]
The Scientific World Journal, 2014 The research on damages of structures that are supported by deep foundations has been quite intensive in the past decade. Kinematic interaction in soil-pile interaction is evaluated based on the p-y curve approach. Existing p-y curves have considered the

Applied Sciences, 2022 The removal of soil during scouring is crucial to the lateral resistance of piles in bridges of railways or highways. In this process, dilatancy of the interface soil induces variation in normal stress, which in turn influences the interface soil lateral

Evaluation of sand p–y curves by predicting both monopile lateral response and OWT natural frequency
Studia Geotechnica et Mechanica, 2022 Extending the use of the p–y curves included in the regulation codes API and DNV to design large-diameter monopiles supporting offshore wind turbines (OWTs) was unsuccessful as it resulted in an inaccurate estimation of the monopile behavior.

Nonlinear finite element Analysis of laterally loaded piles in Layered Soils
Electronic Journal of Structural Engineering, 2023 This work is based on Winkler’s theory to analyze laterally loaded single piles using the finite element method. Soil nonlinearity is taken into account via nonlinear springs “p-y” curves. Exact element displacement shape functions and stiffness matrix

Cyclic overlay model of p–y curves for laterally loaded monopiles in cohesionless soil [PDF]
Wind Energy Science, 2023 The bearing behaviour of large-diameter monopile foundations for offshore wind turbines under lateral cyclic loads in cohesionless soil is an issue of ongoing research. In practice, mostly the p–y approach is applied in the design of monopiles. Recently,

Modified p-y Curves Method Based on Degradation Stiffness Model of Sand
Shanghai Jiaotong Daxue xuebao, 2020 Most of the existing p-y curves are based on the model test results of small-diameter pile under cyclic loading of finite times, which makes it difficult to accurately describe the displacement accumulation of large-diameter pile under long-term ...

Investigation of p-y Behaviors of a Cyclic Laterally Loaded Pile in Saturated Silty Sand
Advances in Civil Engineering, 2022 This study aimed to evaluate the p-y behavior of pile foundations installed in saturated silty sand subject to cyclic lateral loading. Model piles were installed in saturated silty sand with three relative densities (40%, 70%, 90%), and lateral loads of ...

A Numerical Investigation to Determine the p–y Curves of Laterally Loaded Piles
Mathematics, 2021 This paper focuses on a numerical approach to finding the p–y curves for laterally loaded piles. The Drucker–Prager plastic model is employed and implemented within a finite element MATLAB code.

Numerical Study on Lateral Response of Offshore Monopile in Sand under Local Scouring Conditions
Journal of Marine Science and Engineering, 2023 Currently, p-y models have been broadly adopted for estimating the lateral bearing capacity of large-diameter monopiles in offshore engineering. However, the existing p-y curves cannot reflect the effect of pile diameter D on the lateral response of ...

Shallow-layer p-y curves for single micropile in sands
Yantu gongcheng xuebao, 2018 Micropiles are increasingly used in seismic design or retrofitting for pile foundations. This study aims to investigate the validity of the widely used p-y relationships proposed by the American Petroleum Institute (API) and the ‘m method'; in the ...
