Strength and Stiffness Characteristics of Steel Ladder-Type Cable Trays
Ladder-type cable trays identical with the as-built are generally tested to establish their strength and stiffness characteristics. Test data for systems in operating plants, however,...

Composite-System Approach for Seismic Analysis of Secondary Systems
An accurate and efficient method for seismic analysis of multiply supported, multi-degree-of-freedom secondary subsystems is developed. The method accurately accounts for the effects of...

Development of Concrete Nuclear Containment (ACI 359) Code Requirements as they Relate to Probability Based Load
The historical development of the load combinations used in concrete containment is presented in the paper. These load combinations are examined and identified in the light of the reasonable,...

Containment Capability
Section 2. 0 of this report contains a description of analysis methods for the containment structure. Testing on containment models and sections of containments is described. Section 3....

Sodium Concrete Reaction ? Structural Considerations
An overview of the sodium concrete reaction phenomenon, with emphasis on structural considerations, is presented. Available test results for limestone, basalt, and magnetite concrete with...

Slurry Pipeline Control Systems
The paper documents the La Perla-Hercules pipeline and its control system. This eight and fourteen-inch, 382-kilometer iron ore concentrate slurry pipeline was commissioned in June of...

Design and Performance of Buried Fiberglass Pipes ? A New Perspective
The buried performance of fiberglass pipes was the subject of a comprehensive and multifaceted research program carried out in 1982 and 1983. Instrumentation, capable of accurately tracing...

Performance of Low Stiffness Plastic Pipe in Stiff Soils
Large diameter pipe made from ductile plastics, such as polyvinyl chloride (PVC), polypropylene (PP) and high density polyethylene (HDPE) can be effectively utilized in subsurface installations...

The Present Status of Application of the Plastic Concepts in Structural Design
The different approaches of recognizing plastic behavior in the design of steel structures are reviewed and the design requirements that assure successful utilization of this behavior...

Testing for Salt Damage
Salts used to melt snow can contribute to deterioration of concrete structures. Various tests were used to determine the extent of damage in two structures in Rochester, N.Y. One is an...

In-Plane Composite Drains
Drainage of water from outside basement walls, behind retaining walls, or highway cut or fill slopes, has long been a problem. A common solution is the aggregate drain. Often, installation...

The New Art of Structural Engineering
Exerpt from The Tower and the Bridge: The New Art of Structural Engineering describes the career and the accomplishments of Thomas Telford,...

Engineering Mechanics in Civil Engineering
The principles of engineering mechanics and the application of these principles to civil engineering problems cover a broad spectrum of topics ranging from theory to practice. These proceedings...

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,...

Computer Aided Design of Reinforced Concrete
An interactive computer-aided design (CAD) program for the design of reinforced concrete members is herein described. The program, called ECPRS, designs reinforcement and performs all...

Dredge Spoil Disposal Predictions and Performance: A Case History
A 146-acre dredge spoil disposal facility was constructed in Baltimore Harbor that received 3. 4 million cubic yards (2. 6 million cubic meters) of dredge spoil generated from construction...

Perspectives on Modelling Consolidation of Dredged Materials
The physical and mathematical aspects of this problem are highly nonlinear and material-property relationships extend beyond the scope of standard geotechnical engineering. The potential...

Sedimentation and Self Weight Consolidation of Dredge Spoil
Test results suggest that self weight consolidation begins when an interface forms in the settlement column and the slurry reaches a critical concentration as a result of the solid particles...

Dredged Slurry Stabilization for Seagirt Marine Terminal
The Seagirt Marine Terminal is constructed on reclaimed land on dredged spoil from the I-95 Fort McHenry Tunnel in Baltimore, Maryland. Three stabilization procedures considered applicable...

Prediction of Viable Tailings Disposal Methods
A sand-fines-water diagram is proposed to analyze and describe slurries composed of coarse and fine particulate matter. The diagram can be used to predict and plan disposal methods for...
