System Reliability Analysis of Defected Pile group Foundations
… This thesis studies the behavior of defected pile group foundations installed in sand and calibrates the resistance factor of pile group foundation, utilizing a rational based system reliability analysis. This was achieved by conducting a comprehensive numerical parametric investigation using …

Full-Scale Lateral Load Test of a 3x5 Pile Group in Sand
Although it is well established that spacing of piles within a pile group influences the lateral load resistance of that group, additional research is needed to better understand trends for large pile groups (greater than three rows) and for groups in sand. A 15-pile group in a 3x5 configuration …

Full Scale Static Lateral Load Test of a 9 Pile Group in Sand
… study the effects of spacing in laterally loaded pile groups and how the pile spacing affects lateral resistance of the piles. In this test a 9-pile group of steel piles was installed in a 3x3 configuration in sand. The piles were spaced from center-to-center at a distance of 5.65 pile diameters …

Full-Scale Lateral-Load Tests of a 3x5 Pile Group in Soft Clays and Silts
… of static lateral load tests were conducted on a group of fifteen piles arranged in a 3x5 pattern. The piles were placed at a center-to-center spacing of 3.92 pile diameters. A single isolated pile was also tested for comparison to the group response. The subsurface profile consisted of cohesive …

Statnamic Lateral Loading Testing of Full-Scale 15 and 9 Group Piles in Clay
… of seismic and impact loading on foundation piles is an important and a focused interest in the engineering world today. Because of seismic and other natural events are unpredictable, uncontrollable and potentially unsafe it is a vital study to understand the behavior and relationship …

Análise de estaqueamento pelo método das cargas limite
… We analyse thereafter the possible types of pile failure and develop studies which allow us to apply the elastic-plastic method to piling design. We may obtain then a redistribution of the load of the most highly loaded piles to the others, according to the pile group characteristics and to …

Implementation of an anisotropic plasticity model and its application to pile foundations problems
Pile foundations are used in more challenging site conditions, such as soft soils, to ensure both sufficient capacities and desired performance. As construction moves to more problematic locations and demands increase in magnitude and complexity, pile foundations have been required to accommodate …

Dynamic Full-Scale Testing of a Pile Cap with Loose Silty Sand Backfill
Pile caps are used in foundation design to aid multiple single piles to act as a pile group to resist lateral forces that may cause overturning moments. The pile cap and pile group resist these forces by pile-soil-pile interaction, base and side friction along the pile cap-backfill interface, and …

Investigation of the Resistance of Pile Caps to Lateral Loading
… deep foundations. These foundations consist of groups of piles coupled together by concrete pile caps. These pile caps, which are often massive and deeply buried, would be expected to provide significant resistance to lateral loads. However, practical procedures for computing the resistance of …

Seismic Behavior of Pile -Supported Bridges
… interaction in seismic analysis of pile-supported bridges. The proposed model is applied to perform seismic performance evaluation of the Cairo Bridge for different excitation intensities and to identify an appropriate retrofit strategy for the bridge. Applications of the pile group …

Behaviour of single batter piles and pile groups under lateral soil movement in sand
Piles are commonly subjected to induced loads from nearby construction activities such as approach embankments, excavation, tunnelling and moving slopes. To better understand the mechanism of this complicated soil-pile interaction problem, a comprehensive experimental and numerical program were …

Full-Scale-Lateral-Load Test of a 1.2 m Diameter Drilled Shaft in Sand
… drilled shafts and a 0.324 m diameter steel pipe pile in sand. Although the tests involve two different foundation types, the upper 2.4 m of the profile, which provides the majority of the lateral resistance, consists of sand compacted around both foundation types. Therefore, these test results …

Behavior and efficiency of perimeter pile groups
Groups of piles are commonly used as high capacity foundations. It is recognised that the load distribution among piles in a group will vary and it is thought that the inner piles are likely to make a relatively small contribution to the total load carried. The essence of the research undertaken is …

Numerical and physical modelling of piled rafts on soft clay under combined loading
Piled raft foundations are typically used in cases where a shallow foundation is inadequate to sustain the loads of the superstructure either because of lack of capacity or because of excessive displacement. They consist of two components, namely the raft and the pile group, contributing to the …

Numerical modeling of a bridge system & its application for performance-based earthquake engineering
… bridge deck collapse due to joint unseating to pile and abutment foundation failure due to lateral spreading. In most of these cases, soil pile-structure interaction (SPSI) has played an important role. SPSI is affected by soil conditions (e.g., competent soil or liquefiable soil) and loading …

The axial behaviour of piled foundations in liquefiable soil
… The axial resistance which can be mobilised by piled foundations in liquefiable soils when subjected to strong shaking remains highly uncertain, and a number of piled foundations have failed in strong earthquakes as recently as 2011 . The lack of visible foundation distress in many such cases …

Seismic Response of Pile Foundations in Soft Clays and Layered Soils
Pile foundations are widely used to support large engineering structures by transferring loads to deeper layers of soil. During earthquakes, in addition to the axial loads, pile foundations are subjected to inertial loads and kinematic loads due to the motion of the superstructure and the …
