Analysis of Pipe Pile-Pile Cap-Superstructure Ground Motion Response

Advanced Materials Research, 2011
Measure the test points of the natural frequencies, the Fourier amplitude spectrum, power spectrum and other parameters by enter different types and frequencies of seismic waves and the stimulation of white noise in the pile shaking table test and seismic wave propagation in the model pipe. Analysis of the transfer law of seismic waves in the pipe pile-

Three-dimensional analysis of pile caps

Computers & Structures, 1992
Abstract A general three-dimensional elasticity solution of pile caps with symmetrically placed column and piles has been presented and illustrated by application to pile caps with two and four piles. The solution of the governing differential equations of three-dimensional elasticity theory has been expressed in the form of a Galerkin vector.

Concrete Filled Steel Tube Piles to Concrete Pile-Cap Connections

Structures Congress 2012, 2012
This paper describes preliminary findings from a Montana Department of Transportation (MDT) funded project focused on testing the seismic performance of concrete filled steel tube (CFT) pile to concrete pile-cap connections. These connections are common/critical components of the support structure for highway bridges in Montana and across the country ...

Behavior of model steel H-pile-to-pile-cap connections

Journal of Constructional Steel Research, 2013
Abstract Steel H-shaped piles are widely used in bridge foundations, but studies on their connections with reinforced concrete pile-cap are quite limited. This paper reports experimental results from monotonically loaded static tests on model steel H-pile to pile-cap connections,in which the piles were subjected to tensile loading or horizontal ...

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 ...

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 ...

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 ...

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.

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.
