Evaluation of Non-Ductile Drilled-in Expansion Bolts
This paper provides background and justification for the design of closely spaced non-ductile drilled-in expansion bolts (bolts). It describes testing used to establish allowable design...
Role of a Standard in the Production of Drilled Shafts
The preparation of drawings and documents that describe the details of the installation of drilled shafts for a project requires an up-to-date standard. The role of the standard in the...
Geotechnical Perspective?Proposed Drilled Shaft Standard
In the writer's understanding, a standard is an agreed upon manual of practice and as such, sets the level of performance and attainment considered adequate. A standard is...
A Structural Engineering Perspective for Drilled Shafts
This commentary is an attempt to close the gap between the Building Code Requirements for Reinforced Concrete (ACE 318-83) and the design of drilled shafts. The context of design includes...
ASCE Drilled Shaft Standard: University Perspective
A critique is presented of the proposed ASCE standard on drilled shafts. Areas where major work is necessary relate primarily to the shaft design sections, establishment of loads, and...
Standards and the Contractor
The International Association of Drilled Shaft Contractors have written their own standards and have cooperated with other groups in similar activities. The author gives his ideas about...
Government Agency Perspective on Standard for Drilled Shafts
Relative to the proposed ASCE standard for Design and Construction of Drilled Shafts, the Tennessee Valley Authority (TVA) would be considered an 'owner'. However,...
Analysis and Design of Pile Foundations
Piles are one of the oldest type of foundation system known to man and as such have been previously studied in depth based on available modeling and monitoring techniques. An increased...
Oil Platform
The Cerveza offshore drilling platform demonstrates that a single-piece platform base for deep water is technically feasible and economically practical. The template-type fixed platform...
Artificial Islands
Artificial islands constructed from gravel fill have become a preferred approach to drilling for oil in hostile Arctic environments. These man-made islands are being built to serve as...
Design of Manmade Offshore Islands for Ice Forces
Approximately sixty percent of the undiscovered oil and fifty percent of the undiscovered gas probably lies in the sedimentary basins offshore Alaska (USGS 1980). Because of this hydrocarbon...
The Deep-Shaft Process: Bright Future for Treating High-Strength Wastewaters
A Deep-Shaft wastewater treatment process may reduce by 10 to 30 percent the power requirements and land area needed for a plant. The technique is most attractive for treating high-BOD...
Drilled Piers and Caissons
Drilled piers, also called drilled caissons, drilled shafts, bored piles, and cast-in-situ piles, have recently undergone a period of growth in their use as foundation bearing elements,...
World's Tallest Offshore Platform Stands in 1025 Ft of Water
During the summer and fall of 1977 and 1978, Shell Oil installed the world's deepest drilling and production platform in water. Located in 1025-ft of water at the Cognac tract...
The Modernization of a Small Hydro Plant
The Cornell Hydro in Northern Wisconsin was torn down, rebuilt, re-equipped and put into profitable operation. After extensive structural modifications to the old plant, three new 10,000...
Preview�1976 Offshore Technology Conference
In this Eighth Offshore Technology, the 300 papers and 1,300 exhibitors will be related to such topics as semi-submersible drill rigs, pollution avoidance devices, equipment protection,...
Earth Retention by Drilled Reinforced Concrete Caissons
A hillside fill is stabilized by the construction of drilled reinforced concrete caissons. The fill supports a building which houses equipment important to a manufacturing process. Other...
