Simplified p-y curves under dynamic loading in dry sand

Soil Dynamics and Earthquake Engineering, 2018
Abstract The behavior of soil-pile systems subjected to dynamic loads in dry sand was investigated using experimental tests. The focus of this study was to quantify the simplified dynamic p-y curve for pseudo-static analysis from model tests under various loading frequencies. A framework for determining the p-y curve on the basis of 1 g shaking table

Experimental Evaluation of p-y Curves Considering Development of Liquefaction

Journal of Geotechnical and Geoenvironmental Engineering, 2013
AbstractAlthough 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.

Lateral Pile Response and p-y Curves From Centrifuge Tests

Offshore Technology Conference, 1983
ABSTRACT Cyclic lateral load tests on model pipe piles driven in inundated, saturated sand were conducted aboard the Cambridge University geotechnical centrifuge. The tests provided qualitative and quantitative data on the interaction between pile and sand.

Slope effect on dynamic p–y backbone curve in dry sand

Soil Dynamics and Earthquake Engineering, 2021
Abstract 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.

Determination of P-Y Curves Using Inclinometer Data

Geotechnical Testing Journal, 1994
Abstract Derivation of p-y curves from lateral load tests on deep foundations is a tedious and expensive task, requiring large numbers of strain gages along the length of the pile to develop bending moment versus depth relationships. A method is proposed which allows derivation of p-y curves from simple inclinometer data using a least ...

Theoretical p-y Curves for Laterally Loaded Single Piles in Undrained Clay Using Bezier Curves

Journal of Geotechnical and Geoenvironmental Engineering, 2010
An alternative method was introduced for predicting the nonlinear p-y curves for monotonic unidirectional laterally loaded single piles in uniform undrained clay. On the basis of numerical studies, closed-form solutions were developed for locating the start of yield (y e ); the ultimate yield point (y u ); and the initial stiffness, K i of the p-y ...

Uncertainty about p‐y Curves for Piles in Soft Clays

Journal of Geotechnical Engineering, 1986
Criteria for estimating the first two probabilistic moments of the normalized parameters of p-\Iy\N curves are presented. These parameters are the ultimate soil resistance and the initial tangent value of the soil reaction which are both normalized with respect to the values predicted by an adequate mathematical expression.

A method for p-y curve based on Vesic expansion theory

Soil Dynamics and Earthquake Engineering, 2020
Abstract 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.

Prediction of P-Y curves from finite element analyses

1986
The prediction of P-Y curves for undrained clay and sand based on the results of finite element analyses is presented in this thesis. A higher-ordered finite element program was used in the analyses. The ability of the program to accurately model the undrained soil condition was verified by comparing predicted load-deflection responses with closed ...

Lateral Force–Displacement of Piles—p-y Curve

2017
Many types of loading such as those induced from earthquakes, wind, ocean waves, traffic (bridges), thermal movement, water pressures (dams), and blast loads can generate lateral forces on vertical piles with a direction perpendicular to the axial direction of piles.
