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...

A Correlation Study on the Spectrum Decomposition Method
The major elements of the Spectrum Decomposition Method (SDM) are reviewed together with its automated process for generation of in-equipment response spectra (IERS). The floor required...

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...

Centrifugal Modeling of Pile Foundations
Modeling of pile foundations in a centrifuge, where the self weight induced stresses in the soil are simulated by elevated gravity loading, is described. Hollow pipe piles in a stiff clay...

A Flat-Dilatometer Study of Lateral Soil Response
The effect of flat dilatometer penetration on the lateral stress conditions in soil around the dilatometer blade and the soil response against dilatometer diaphragm deflection were investigated...

Dynamic Stiffness of Pile Groups
A number of procedures have been proposed for the dynamic analysis of complete pile foundations including group effects. Most of these introduce some sort of approximation to reduce the...

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...

Study on Secondary Compression of Clays
An elastoviscoplastic constitutive model shows that a strain rate effect parameter is related to the coefficient of secondary compression. The relation was verified experimentally by test...

Consolidation Performance of Soft Clays: Part 1. Model
The simplified version of the soil model used in the finite element scheme is a linear anisotropic elastic model. Part 1 defines the parameters needed for the model and the laboratory...
