Reduction Factors for Laterally Loaded Pile Groups Accounting for Pile Cross Sections and Soil Properties [PDF]
Civil Engineering Infrastructures Journal, 2022 P-y analysis approach is among the most widely used methods implemented for simulating the pile behavior under lateral loading. To obtain the p-y curve of a pile group, that of a single pile should be modified by a group reduction factor which is ...

Journal of Marine Science and Engineering, 2023 With the rapid increase in offshore wind turbines in China, monopiles with diameters exceeding 2 m are widely used. As these piles are subjected to lateral loads caused by wind, waves, and currents, the designs of the pile foundations supporting the ...

Non-linear Analysis of Laterally Loaded Piles Using "p-y" Curves [PDF]
Geotechnical and Geological Engineering, 2020 In this paper, we analyze the behavior of a monopile under lateral loading. Specifically, this work focuses on the examination of the static stiffness coefficients of a monopile vertically embedded in a homogeneous or multilayer soil of random geometry and random mechanical properties.

Numerical study on the influence of installation effect on laterally loaded piles in sand
Shenzhen Daxue xuebao. Ligong ban, 2023 In order to study the influence of the installation effect caused by pile penetration into a sand foundation on the pile horizontal bearing capacity, we establish a numerical model to simulate the penetration process and the horizontal loading process of

Behavior of CFA and H-section steel piles in lateral loading: experimental and numerical analysis
Revista IBRACON de Estruturas e Materiais, 2021 : The behavior of continuous flight auger (CFA) piles and steel H-section piles to lateral loading is investigated using numerical analyses supported by field tests. A three-dimensional finite element numerical model to lateral load is presented.

Multi-directional cyclic p–y curves for soft clays [PDF]
Ocean Engineering, 2016 Abstract Currently there is a lack of information and experimental data to formulate p–y curves in multi-directional loading conditions for soft clays. Experimental evidence has shown that uni-directional p–y curves are not able to represent correctly the near field soil response to multi-directional earthquake loading.

Finite Element-Based p-y Curves in Sand
Arabian Journal for Science and Engineering, 2023 P-y curves are used in the prediction of non-linear soil resistance resulting from the horizontal pile movement. Many of the p-y curves have been developed in the 1970s for the petroleum industry to predict the horizontal capacity of piles supporting oil platforms.

An explicit algebraic family of genus-one curves violating the Hasse principle [PDF]
, 1999 We prove that for any t in Q, the curve 5 x^3 + 9 y^3 + 10 z^3 + 12((t^12-t^4-1)/(t^12-t^8-1))^3 (x+y+z)^3 = 0 in P^2 is a genus 1 curve violating the Hasse principle. An explicit Weierstrass model for its Jacobian E_t is given.
