Beams on Elastic Foundations: A New Approach
Using the Vlasov model, Vallabhan and Das have developed an effective iterative technique to solve the beam-on-elastic-foundation problem where the soil is assumed to have a uniform thickness...
Settlement of Strip Foundations on Regularly Jointed Rock Masses
The analysis of a long, rigid strip foundation resting on the surface of a regularly jointed rock mass is presented. Two models of the overall rock mass are investigated; one in which...

A research effort within the electric utility industry has focused on unified design methods for axially loaded foundations for transmission line structures. This research has been made...
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...
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...
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...
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....
Seismic Response Considerations in Foundation Design
There are no generally accepted procedures to determine the potential magnitude of reduction of footing bearing capacity that may result from soil strains or pore pressure changes during...
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...
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...
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...
