Interaction of Piles and Cap In Piled Footings

Journal of the Geotechnical Engineering Division, 1980
This note describes a laboratory-scale experimental investigation undertaken to study how the separate ultimate bearing capacities of pile groups and footings (caps) are related to the resulting bearing capacities of the piled footings formed as a combination of group and cap.

Effects of Pile Cap in Single Pile and Lateral Capacity of Pile Group

Advances in Deep Foundations, 2005
This paper describes the results for a numerical analysis of single piles and pile groups in clayey soils subjected to monotonous lateral loading using the ABAQUS finite element software. The investigated variables in this study include free head and embedded capped single piles, pile diameter (1.0 m, 0.5 m), pile length (7.0 m, 10.0 m), and pile ...

Pile‐Cap‐Pile‐Group Interaction in Nonhomogeneous Soil

Journal of Geotechnical Engineering, 1991
A numerical method of analysis is presented to study the behavior of vertically loaded pile groups embedded in a nonhomogencous soil with the pile caps in contact with the ground. The considered soil profiles consist of soil with Young's moduli increasing linearly with depth.

Behavior of a Nine-Pile Group with and without a Pile Cap

Contemporary Topics in In Situ Testing, Analysis, and Reliability of Foundations, 2009
The lateral load-displacement behavior of a pile group is a function of the number of piles and their individual stiffnesses, the non-linear response of surrounding soils, and pile spacing. The load-displacement behavior of pile groups also depends upon the degree of pile head restraint provided by the cap and the associated frame action provided by ...

Integrity Testing of Three Model Piles with a Pile Cap

Journal of Testing and Evaluation, 2018
Abstract Nondestructive pile integrity testing (PIT) methods based on the propagation of sonic/ultrasonic waves have been widely used for the quality assurance of newly constructed drilled shafts. However, application of these techniques for forensic investigations of existing piles may encounter difficulties that are due to the ...

Simulated Seismic Load Tests on Prestressed Concrete Piles and Pile-Pile Cap Connections

PCI Journal, 1990
The results of tests conducted in New Zealand on prestressed concrete piles and pile-pile cap connections subjected to simulated seismic loading are summarized. The piles were of prestressed pretensioned concrete with a 400 mm (15.7 in.) octagonal cross section and contained spiral reinforcement. The pile caps were of reinforced concrete.

Nonlinear Buckling Analysis of Piles with High-Rise Pile Cap

Deep Foundations and Geotechnical In Situ Testing, 2010
To study the buckling stability of piles with high-rise cap widely used in bridge and harbor engineering, the advantages as well as the insufficiency of traditional analysis methods (e.g., the method using the minimum potential energy theory and variational method by treating the pile shaft as ideal axially-compressed bars) were first discussed.

Seismic performance of prestressed concrete piles and pile-pile cap connections

1987
The performance, strength and ductility of prestressed concrete piles, and their connection to pile caps, subjected to severe seismic loading are investigated in this thesis. Knowledge of the strength and ductility of the pile within its embedded length in the foundation material is of importance due to the large deformations which can occur during an ...

Effect of Pile Layout and Pile Cap Thickness on Load Distribution in Piles

2018
The paper illustrates, through practical examples, the effect of pile layout and pile cap thickness on the load distribution among different piles in a pile group. Study has been done considering square and rectangular pile cap configurations with different pile cap thickness being considered for each pile arrangement pattern.

A variational approach for the analysis of pile group–pile cap interaction

Géotechnique, 2000
This paper presents a variational approach for the analysis of pile groups having rigid pile caps in contact with the ground. The pile groups are assumed to be embedded in an isotropic elastic half-space. Both the deformations and shear stresses of group piles are each represented by a finite series with a set of undetermined constants, and Mindlin's ...
