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...

Seismic Response Study of Two Memphis Sites
This paper presents a study to evaluate the soil effects on earthquake ground motion of two selected sites in the Memphis area. Twenty artificial bedrock acceleration time histories with...

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...

Human Factors and Communication Problems in Foundation Engineering
Recent findings in non-engineering fields related to human factors are reviewed with emphasis on communication difficulties. Foundation engineering tasks are discussed in the context of...

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...

Performance of High Capacity Caissons Founded on Decomposed Rock
The results of six load tests on large diameter caissons founded on decomposed rock are presented and analyzed. The caissons ranged from 1.5 m to 2.5 m in diameter and were 20 m to 23...

Rectangular Footing on Nonhomogeneous Elastic Half Space
The problem of a rectangular footing or a strip footing on a nonhomogeneous elastic half space is studied in this paper. The medium is assumed to be isotropic with a variable shear modulus...

Effect of Void on Footing Behavior Under Eccentric and Inclined Loads
The effect of underground void on the behavior of strip footings subjected to eccentric and inclined loads was investigated using the finite element method of analysis. Results of the...

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...

Statistical Analyses of Drilled Shaft and Embedded Pole Models
In recent years a significant effort has been made by the Electric Power Research Institute (EPRI) to develop new design models, to collect and summarize existing load test data and to...

Long Term Performance of High Rise Mat Foundation
The vertical movement of the foundation soils for a multi-story high rise office tower was monitored during foundation excavation, tower construction and the 25-year in-service period...

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...

Response of Concrete Island Drilling System to Ice Impact Loading
The lateral stability and load/deformation characteristics of the Concrete Island Drilling System structure under ice impact loading conditions were studied. The 300-foot-square (91.5-meter...

The Role of Analytical Geomechanics in Foundation Engineering
The role of modern geotechnical analysis in foundation design is reviewed, and analysis methods are classified into three categories, depending on their level of sophistication. The benefits...

Reliability in Foundation Engineering Practice
The value and use of reliability concepts in foundation engineering practice are explored, with a focus on two complementary approaches. In the first, macroscopic and action-oriented,...
