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...

Transient Dynamic Response Analysis of Embedded Rigid Foundations
A simplified approach for the transient dynamic response analysis of embedded multiple rigid foundations is presented. The approach is based on approximate time-domain formulations of...

Subgrade Model for Static and Dynamic Response Analysis of Surface Foundations
A new subgrade model is presented for the static and dynamic response analysis of surface foundations. The model consists of a number of horizontal layer model units. Each model unit is...

Foundation Studied for Turbine-Generator on Liquefiable Soils
Turbine-generator foundations are generally constructed of concrete in the U.S.A. This paper deals with the dimensioning and evaluation of a turbine foundation in Oxnard, California. The...

Effect of Site Soil Properties on Seismic SSI Response of Embedded Structures
In a series of two-dimensional soil-structure interaction (SSI) analyses, seismic responses, including the SSI effect of a deeply embedded reactor building of a standard plant in different...

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...

Movement Control of Excavation Support Systems by Iterative Design
Conventional design practice for excavation support systems emphasizes determination of loads and selection of structural components. This paper presents a method which uses movement control...

Some Expert System Applications in Geotechnical Engineering
Knowledge-based expert systems (KBES) represent a new technology for computer-aided engineering. These systems can be useful in situations which involve expert judgments for effective...

Geotechnical Judgment in Foundation Design
This paper summarizes the initial findings of a research project to investigate the judgment-making process of foundation engineers. Solutions for a typical design problem were solicited...

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...

Performance of a Large Ribbed Mat on Cohesive Soil
The performance of a 678-ft by 304-ft (207-m by 93-m) ribbed concrete mat was studied to provide improved soil input parameters for design. The mat was constructed on a low plasticity...

Performance of Different Retention Systems in Similar Soils
Performance behaviour of three deep braced excavations in a similar soil profile, in the Chicago area is described. At each site, different bracing systems were utilized. Methods used...

Field Performance of a Soil Nail System in Loess
This paper presents data from measurements of a soil nail system constructed in loess soil in Pullman, Washington. The soil nail system is designed to retain a 39.2 ft (11.9 m) high excavation...

Analysis of Drilled Shafts in a Deep Fill
A deep fill of varying thickness will settle with time and will also exhibit a horizontal component of movement. Drilled shafts that are installed in the fill to support a structure must...

Performance of a Building Foundation Designed to Accommodate Large Settlements
The Eastern Airlines shuttle terminal at LaGuardia Airport in New York City is supported on spread footings founded in an incinerated refuse fill which overlies a deep deposit of slightly...

Sensitivity Study of the Cyclic Axial Capacity of a Single Pile
Evaluation of the axial capacity of an offshore pile subjected to a severe North Sea storm is presented. Effects of using different degradation criteria, upper and lower bound interaction...

Underwater Foundations for a Jack-up Barge
Innovative underwater foundations were developed to provide a solid base for the legs of a large jack-up barge needed by General Dynamics to transport heavy components from Quonset Point,...

Thoughts on the History and Current Practice of Foundation Engineering in North America
With the publication of 'Erdbaumechanik' in 1925, the behavior of soils was explained in terms of numerical physical properties and the principles of what became...

Integration of Research Into Design Practice
A widely held perception is that research results flow from the research community along the paths of professional publication into the design offices, where they find practical application....

A Case Study of Ebb Tidal Delta Equilibrium: Ocean City, Maryland
The inlet at Ocean City, Maryland was created by hurricane surge breaching of Fenwick Island Spit in 1933. Inlet stabilization was completed in 1934-1935. The inlet jetties have been held...
