Geotechnical centrifuge model testing for pile foundation re-use
… becoming more and more congested with redundant foundations. As the underground development of services and infrastructure already confines the location of building foundations, redundant foundations only add to this problem. The research described in this thesis, using centrifuge model testing, …

Effect of deep excavation on an adjacent pile foundation
… studies the behavior of single axially loaded pile located close to a 30m deep braced excavation in Marine Clay corresponding to site conditions of the Kallang formation in Singapore. Parametric analyses were carried out, using non linear three-dimensional finite element methods (with Plaxis …

FOOTING FIXITY OF BRIDGE PIER WITH END-BEARING PILE FOUNDATION
… the pier footing on multiple rows of end-bearing piles case. A comprehensive study using 20 models derived from the pier-pile design example presented by FHWA is developed for the finite element analysis using computer software. In order to investigate the difference of G values for different pile …

Impact of Jet Grouting on the Lateral Strength of Soil Surrounding Driven Pile Foundations
… used to strengthen the soft soil surrounding the piles and the pile cap of two full-scale driven pile foundations. Soilcrete columns, created by jet grouting, were placed underneath the pile cap and surrounding the piles of the first foundation. Two rows of soilcrete columns were placed around the …

Um modelo semi-analítico em elementos finitos para interação inercial em análise sísmica
… for seismic inertial analysis of structures with pile foundation is presented here. The properties of the elements are stablished through the elastic Mindlin's formula. The results of the analysis of a typical vent stack of a nuclear power station, for a simplified accelerogram is shown also.

Recalques de fundações em estacas
… with methods for settlements prediction of pile foundation, and estabilishes a few comparisons with field data. Main methods were grouped into: conventional methods; methods based on theory of elasticity; and empirical procedures based on settlement of pile groups. Stress was given upon …

Experimentelle Untersuchungen zur Verformungsakkumulation und Tragfähigkeitsreduktion von zyklisch belasteten Pfählen
… with the effects of wind and waves, the foundations for offshore wind turbines are exposed to cyclic and dynamic loads. In this respect, different types of driven pile foundations, either the monopile or the multi-pile foundation, are frequently envisaged as foundation systems. Depending …

Investigations of Pile Foundations in Brownfields
… to clean, improve and protect the environment. Piles foundations are often used in Brownfields to support structures. Regulators are concerned about the environmental safety of pile foundations in Brownfields sites. Piling in Brownfields may lead to transport of contaminants from the …

Finite element analysis of some soil-structure interaction problems
… (rectangular) plate element, and nonlinear foundation represented by a series of springs. The behavior of the latter is simulated by using a special form of the Ramberg-Osgood Model. The nonlinear analysis is performed by using an incremental iterative scheme. The procedure is used to …

An Investigation and Comparison of Accepted Design Methodologies for the Analysis of Laterally Loaded Foundations
Single piles and pile groups are frequently subjected to high lateral forces. The safety and functionality of many structures depends on the ability of the supporting pile foundation to resist the resulting lateral forces. In the analysis and design of laterally loaded piles, two criterions usually …

Response of soil–foundation–structure interaction of tall building (frame-wall) structural system under seismic effect
… analysis techniques of estimating the soil -foundation-structure interaction (SFSI) lead to either simplifying or ignoring this interaction. The structural and geotechnical engineers consider the foundation effect on the multi-story building design. Where both the structural and geotechnical …

Assessment of Seismic Behaviour of Large LNG Tanks Considering Soil-Foundation- Structure Interaction
… of LNG transportation and storage. Often the foundation soil in coastal regions is not capable of bearing the load of such heavy structures. Thus usually, deep foundations are used to support these tanks. Indeed, pile foundations are commonly used for these large tanks to transfer the load to …

A Multicriteria Based Quantitative Framework for Assessing Sustainability of Pile Foundations
… multicriteria based sustainability indicator for pile foundations is developed that will aid the design and decision making processes of pile foundation projects. Specifically two types of pile foundations, namely, the driven concrete pile and the drilled shaft, are considered. The impacts these …

Performance of short piled raft foundation system on peat soil under static load
… In recent years, there is no special established foundation structure for peat yet, without any treatment of soil. Thus, notably for a depth of 3 to 10 m of the peat layer, there is a challenge to develop a foundation system on peat without any stabilization nor remove and replace, especially for …

Full-Scale-Lateral-Load Test of a 1.2 m Diameter Drilled Shaft in Sand
… models associated with laterally loaded deep foundations have typically been based on load tests involving relatively small diameter foundations. The lateral soil resistance for larger diameter foundations has been assumed to increase linearly with diameter; however, few, if any load tests …

Performance of foundations in a rising groundwater environment
… such an increase in pore pressure would have on foundations in overconsolidated clay was investigated. The performance of foundations in stiff clay during a rising ground water event was investigated by means of centrifuge model tests. The model tests included comparisons of the behaviour of …

Seismic Analysis and Response of Highway Bridges with Hybrid Isolation
… demand on critical members such as columns and foundations, but hybrid isolation also reduces superstructure displacements and the corresponding size of abutment movement joints. A key factor, however, to the success of hybrid isolation (where isolators are placed only at the abutments) is the …

Scaling effect in cone penetration testing in sand
… a device which provides a small scale model of a pile foundation. Early versions were simple cone points for which the only measurement was the thrust required to push the point through the ground. Over the past 20 years, the cone was standardized to a tip area of 10 cm², and an electrical version …
