Analysis of the pile-to-cap connection of pile caps on two steel piles – An experimental and numerical study

Engineering Structures, 2022
Abstract The objective of this research was to study the mechanical behavior of pile caps on two steel piles submitted to centered loading with different arrangements of the connection between pile and pile cap, as well as evaluate analytical models found in the technical literature. A numerical analysis of a pile cap on two steel piles was performed

Pile Cap-Pile Group-Soil Interaction

Journal of the Structural Division, 1981
A numerical procedure based on the finite element method is proposed for the analysis of structural systems composed of beam-column (pile), plate (cap) and nonlinear springs (soil). It integrates one-and two-dimensional idealizations for these components in order to obtain an approximation to the three-dimensional problem.

The Problem of Pile Group–Pile Cap Interaction

Géotechnique, 1971
Synopsis The Paper presents an elastic analysis of two problems concerning the interaction with the supporting ground of an arbitrarily spaced group of piles, embedded in a smooth ground contacting pile cap of any shape, namely the load displacement behaviour of the system and the load distribution between the piles in the group and the cap.

CFD investigation of the cap effects on wave loads on piles for the pile-cap foundation

Ocean Engineering, 2019
Abstract The cap effects on the wave forces acting on the piles underneath the cap are important for the estimation of the wave loads on the elevated pile-cap foundations of sea-crossing bridges. Full scale 3-dimensional numerical simulations are carried out for large square caps with piles placed at different locations underneath.

Deep Pile Cap with Tension Piles

SP-273: Further Examples for the Design of Structural Concrete with Strut-and-Tie Models, 2010
Deep pile-caps are commonly used in structures. Two approaches, sectional design and Strut-and-Tie Model (STM) design are presented in this paper for designing deep pile-caps under a combination of axial load, shear, and moment that produces tension in some piles.

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 ...
