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...
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...
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 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...
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...
