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...

Risk Correction Factors for Bearing Capacity Analysis
In this paper bearing capacity correction factors are developed to account for the randomness in the load and soil properties. These are applied to the bearing capacity equation in the...

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...

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...

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...

Pile-Drilled Caisson Combination for Foundation of High Rise Building
The analysis and evaluation of several alternatives for foundations of a high rise office building is presented, which resulted in the selection of a combination of high capacity piles...

Combination Drilled Shaft and Driven Pile Foundation for a High-Rise Building
A case history is presented which discusses the design and construction of a combination drilled shaft and driven pile foundation which supports a high-rise in San Francisco. Drilled piers,...

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...

Complex High-Rise Foundation Design and Construction
The substructure design and construction of a 60 story office tower in downtown Chicago is described. The presence of existing belled caissons on hardpan required use of filtered dewatering...

A New Combined Footing and Drilled Shaft Foundation Design
A conventional belled caisson foundation installation in glacial till to support a suburban Chicago 10-story office building was stopped when test caissons revealed excessive water-bearing...

Interaction of Geology, Construction Practice and Foundation Design
The influence of geologic knowledge and construction practices on the geotechnical foundation design process has been assessed and summarized. Particular emphasis has been given to the...

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....

Innovative Foundation Designs for Permafrost Conditions in the Arctic
This paper describes the engineering solution to restore the structural properties of permafrost at a site location in the Western Operating Area of the Prudhoe Bay Field. Steel pile supports...

Ponds and Lagoons of Gulf Islands National Seashore
A physical and natural resource survey was conducted of the ponds and lagoons on Horn and Petit Bois Islands, Gulf Islands National Seashore, Mississippi. Petit Bois Island contains 17...

Status of the Spiny Lobster (Crustacea: Palinuridae) Stocks Off Northeast Brazil in Relation to Fishing Effort and Environmental Conditions
Conditions for the development of relatively abundant populations of spiny lobsters of genus Panulirus, mainly P. argus and P. laevicauda, off Northeast Brazil are consistent with hydrologically...
