Pile foundations for large North Sea structures

Pile Foundations for Large. North Sea Structures. J. de Kuiter and F. L. Beringen. Fugro, B.V.. P.O. Box 63, Leidschendam. The Netherlands. The oil fields in the northern part of the North Sea, with their great water depth and adverse sea conditions, have led to new concepts in the design of pile foundations for production ...


Estimation of fundamental period for structures supported on pile

Results show that the provisions given in ATC may be used for structures supported on shallow footings but may not be applicable for structures supported on pile foundations or foundations having the ratio of lateral to rotational stiffness coefficients different from those of shallow foundations. An equation, similar to the  ...


Design and Construction of Driven Pile Foundations Volume I

This document presents information on the analysis, design, and construction of driven pile foundations for highway structures. This document updates and replaces FHWA. NHI-05-042 and FHWA NHI-05-043 as the primary FHWA guidance and reference document on driven pile foundations. The manual addresses design ...


Seismic Design of Pile Foundations: Structural and Geotechnical

SYNOPSIS Research on soil-pile-structure interaction under dynamic loading over the past 20 years has led to a variety of analysis approaches of varying complexity to address a range of dynamic problems. Many of these analysis approaches have been adapted for use for the seismic design of pile foundations .



In this paper, we propose load and resistance factor design for the structural design of piles in pile foundations for Level 1 earthquake situation. The proposed load factors in the study are a function of the chosen soil investigation/testing and piling method, which is applied to the bending moment in piles. Therefore, better  ...


On Technology of Hydraulic Engineering Structures Pile

The paper presents aims to provide analysis of non-waste technology of producing piled foundations of hydraulic engineering structures. The authors introduce a complexity of additional technical and technological steps making possible to both diminish the work-load and cut the time required. The paper also describes ...

structural system or that will restrict or eliminate free passage of high-velocity floodwaters and waves”; and be constructed of flood-resistant materials. ASCE 24-05 requires that structures in areas subject to high-velocity wave action be supported on piles, columns, or shear walls. Shallow mat or raft foundations may be used ...


Assessment of soil–pile–structure interaction influencing seismic

Both experimental and numerical results indicate that soil–structure interaction amplifies the lateral deflections and inter-storey drifts of the structures supported by floating pile foundations in comparison to the fixed base structures. However, the floating pile foundations contribute to the reduction in the lateral displacements ...


centrifuge tests on pile foundation-structure systems affected by

The paper investigates experimentally the behavior of a structure-footing-four piles system under the action of seismic shaking causing liquefaction of a critical soil layer and subsequent soil flow towards a laterally displacing quay-wall. A series of innovative centrifuge tests explore in parametric fashion the role of this pile.


Technical Supplement 14F--Pile Foundations

Pile Foundations. Purpose. Piles are used to transfer foundation forces through relatively weak soil to stronger strata to minimize settlement. The most likely applications for pile foun- dations in stream restoration and stabilization projects are as support for bank stabilization structures (retain- ing wall) and anchors for large ...

This manual provides design guidance intended specifically for the geotechnical and structural engineer but also provides essential information.


Critical load and buckling of the single pile foundation subjected to

Abstract. In this study, the critical load and buckling of the single pile foundation subjected to the vertical load are investigated. Considering the second-order moment of the soil-structure interaction, the refined model of the single pile foundation is derived. Then, the critical load and buckling phenomenon of the single pile ...


Pile foundation modelling for inelastic earthquake analyses of large

Introduction. Pile foundations are generally used to support structures on soft soil with low bearing capacity. Offshore softs generally fall into this category, and for this reason a major class of pile-supported structures are the Fixed steel platforms used for developing offshore oil and gas. Following the criteria in API- RF2A, ...


Pile Foundation Construction Inspection

Jan 2, 2017 ... Design engineers classify piles according to their Structural Pile Type to reference the structural element to be used for the piles and according to their Geotechnical Pile Type to define a pile's primary mechanism for developing the required bearing. IDOT uses piles to provide foundation support for a wide ...

Research on Pull-out Mechanical Characteristics of Pile Foundation

The submerged floating tunnel is a new tunnel type, with complex structure and requiring high construction demands. While it has been theoretically researched for a long period of time, there is no application example. The uplift pile, with fatal research significance, is the structure foundation of a floating tunnel. The paper ...


Seismic Design of Pile Foundations for Liquefaction Effects

bridge structure may then be determined from inelastic static pushover analyses. Thus, the lateral loads and overturning moments imposed on the foundation by the superstructure may be limited by the lateral strength (with allowance for over- strength) of the support- ing columns or piers. The analysis of the pile foundation  ...

Integral abutment bridges are a special type of bridges that are built without bearings or expansion joints. These bridges are usually subjected to cycles of expansion and contraction that causes horizontal movements of the pile foundations. Accommodating such movements requires some flexibility in the piling system.
