Shallow-layer p-y curves for single micropile in sands

open access: yesYantu 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 ...

Evaluation of sand p–y curves by predicting both monopile lateral response and OWT natural frequency

open access: yesStudia 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.

Modified p-y curves for monopile foundation with different length-to-diameter ratio

open access: yesBrodogradnja : An International Journal of Naval Architecture and Ocean Engineering for Research and Development, 2023
The soil reaction of the monopile foundation subjected to lateral loading in offshore wind turbines is typically assessed relying on p-y curves advocated by API. However, this method is inadequate for gradually increasing monopile diameters and significantly underestimates the lateral soil confinement.

Static and cyclic p-y curves for laterally loaded piles in soft clay

open access: yesYantu gongcheng xuebao, 2017
A pseudo-three-dimensional analysis method on static p-y curves of laterally loaded piles in soft clay is conducted. This method is based on the two-dimensional elastic fictitious loading upper bound limit analysis approach considering the stress-strain ...

Numerical derivation of CPT-based p–y curves for piles in sand [PDF]

open access: yesGéotechnique, 2014
The formulations for the lateral load–displacement (p–y) springs conventionally used for the analysis of laterally loaded piles have been based largely on the back-analysis of the performance of small-scale instrumented piles subjected to lateral load.

Comparative nonlinear analysis of a RC 2D frame soil-pile interaction [PDF]

open access: yesGrađevinski Materijali i Konstrukcije, 2018
Comparative non-linear static (NSA) and non-linear dynamic analyses (NDA) of 2D frames (as parts of skeletal 3D structures) of RC buildings founded on piles are presented in this paper.

Nonlinear Seismic Response of a Long-Span Suspension Bridge Under Sequential Ground Motions Considering Pile Foundation Soil–Structure Interaction

open access: yesCivilEng
This study presents the nonlinear seismic analysis of a large-scale suspension bridge under multiple sequential earthquake records. A detailed 3D finite element model is developed in SAP2000, incorporating CFST pylons, a composite deck, and a main cable ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
