Settlement of Single Piles
This paper presents an application of a recently developed approach for computing the tip settlement of axially loaded single piles driven into compressible layered soil system. In this...
Numerical Analysis of Vertically Loaded Pile Groups
An approach is presented for the analysis of linear and nonlinear response of vertically loaded pile groups. The piles are modeled with finite elements, the pile-soil influence through...
NEWNEG: Microcomputer Program for Downdrag on Piles
A microcomputer program called NEWNEG is presented. It addresses the problem of single piles subjected to downdrag. The analytical background relies on the equilibrium of the pile and...
Ground Failure Damage to Buildings During Earthquakes
Several case histories are examined to evaluate building damage as a function of the foundation type and type and amount of ground displacement. Extensional or vertical ground displacements...
Simplified Seismic Analysis of Pile Foundations
The determination of displacement of the pile cap and displacements and forces of individual piles is essential to the design of pile foundation subject to both static and/or dynamic loading....
Uncertainties in Offshore Axial Pile Capacity
The overall bias and error associated with the API recommended procedures and other popular methods for offshore pile design are evaluated. The paper considers single axial friction piles...
Structural Foundation Practices for Highway Projects
The state-of-practice by State transportation agencies, in the area of structural foundations, is compared between the late 1970's and the present. The structural foundation...
Analysis of Pile Load Tests at Lock and Dam 26
This is a summary of the results collected during the extensive load test program performed by the U.S. Army Engineer District, St. Louis, during the construction of the new Lock and Dam...
Comparative Performance of Two Pile Types
This paper reports on the pile driving and load bearing characteristics of the two pile types driven at a plant site in Sumatra, Indonesia. Nine prestressed concrete piles were driven...
Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...
Augered Cast-in-Place Piles
Development of the augered cast-in-place pile system from origination in the late 1940's to the present state of the art is presented, with methods of pile placement, including...
Bearing Pressure?SPT Correlations for Expanded Base Piles in Sand
Design of enlarged base piles is usually carried out using correlations between SPT N values and point resistance. The results of full scale load tests are used to show that base resistance...
Contribution of Soil Freeze to Pile Capacity
In order to investigate the magnitude and rate of increase in load capacity for piles installed in clayey soils, a series of load tests were performed at various intervals of time following...
Owner and Designer Advantages Derived from Use of Construction Consultant
There are two significant ways that an experienced construction consultant can assist both the owner and the designer/engineer in obtaining an economical and practical structure. Constructibility...
Some Observations on Undrained Side Resistance of Drilled Shafts
A data base of 106 field load tests (65 in uplift and 41 in compression) is used to evaluate the undrained side resistance of drilled shaft foundations. The total stress or alpha (?) method...
New Design Method for Drilled Shafts from Common Soil and Rock Tests
A method is presented by which the compressive capacity and load-settlement characteristics of large drilled shafts can be computed from commonly executed soil and rock tests. The method...
Load Tests on Bored Friction Piles in Clay
For the first time in Boston, Massachusetts, U.S.A., uncased bored friction piles in clay were used to support a six-story residential structure over a 60- to 75-foot (1.83 to 22.9 m)...
Skin Friction Load Test for Caissons in Residual Soils
Results of a load test on a drilled pier are presented. The test was performed to measure only skin friction of a 36 inch (0.91 m) diameter shaft without support at the end. The load test...
Full Scale Caisson Load Test for the Milwaukee Center
Top-down procedures were proposed to construct four basement levels for a major high-rise building development in Milwaukee, Wisconsin. Drilled caisson foundations were the preferred means...
Drilled Shafts?A Database Approach
A database of 43 drilled shaft load tests of high quality has been developed to study parameters that affect the axial behavior of drilled shafts and methods of analysis to predict axial...
