Quick Stroking: A Fast and Accurate Algorithm for Time-Optimal Valve Closure Synthesis
In this paper, a fast, simple, yet effective technique for valve motion synthesis is developed. This technique called Quick Stroking is applied to a practical example problem, and it may...
Pier Review
Upgrading piers to accommodate ships larger than those for which the piers were originally designed is a common problem facing civil engineers. Three case histories illustrate different...
Design of Structures to Resist Nuclear Weapons Effects
This manual provides guidance to engineers engaged in designing facilities intended to resist nuclear weapons effects. Although emphasis is placed on blast-resistant design, other effects...
Vibration Problems in Geotechnical Engineering
This volume constitutes the Proceedings of a two-session Symposium whose main objective is to address geotechnical issues related to vibration problems other than those associated with...
Response of Subsystems on Inelastic Structures
Preliminary analyses are performed to obtain insight into the seismic response of subsystems supported on simple structures that yield during severe earthquake ground motions. Current...
A Study of the Correlation of the Components of Instructure Motions During Earthquakes
Thirty-two buildings are selected that have all three components of motion recorded in the basement, midheight and top of the structure. The correlation coefficients of these motions,...
The Response of Steel Containment Models to Internal Pressurization
To obtain insight and data on the response of containment vessels subjected to beyond design basis accidents, four 1/32 scale steel containment models have been subjected to internal overpressurization,...
Preliminary Analysis of Large Penetration Enclosures for Containment Vessels Subject to Beyond Design Basis Loadings
Numerical simulations of the macro-deformations of the sealing surfaces (gasketed junctures) of a PWR steel containment vessel's equipment hatch subjected to accident loadings...
Bayesian Procedure for Evaluation of Containment Capability
The functional requirements of a steel or concrete containment is to maintain the structural integrity as well as the leak-tight integrity of its pressure boundary under specified design...
Deep River Study - Lower Mississippi River
The current local/federal stalemate over project funding for major dredging projects has deterred U. S. ports in benefiting from the economies inherent in the use of deep-draft ships....
A New Laser Range/Azimuth Position Fixing System
The ATLAS POLARFIX is an entirely new dynamic position-fixing system for short-range, large scale surveys. It is a range/azimuth laser-based system using only a single shore-based tracking...
A New Panama Canal?
The Panama Canal is expected to be obsolete by the end of the century. Already there are serious problems with ship traffic through the Canal: volume of traffic is down, average transit...
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 Ships for Ice Environments
A number of feasibility studies have proven the reliability of marine transportation for the Arctic. Current research and development in this field, especially in the USA and Canada, is...
Methods of Ice Control
Ice control is the practice of holding ice in place or directing its growth and movement. Methods of ice control in navigable waters including locks are presented. Ice carried downstream...
Record Concrete Box Girder Spans Houston Ship Channel
The Houston Ship Channel Bridge is an American advancement of the cast in place, post-tensioned, segmentally constructed, concrete box girder design. In spite of the complex and unique...
Cofferdams Protecting New York Bridges from Ship Collisions
During the past few decades, there have been a number of cases where ships have rammed bridge piers, triggering the superstructure's collapse. The most tragic case was the...
Preventing Another Sunshine Skyway Bridge Disaster
America will not soon forget the tragic collapse of the Sunshine Skyway Bridge into Tampa Bay almost two years ago. That accident was a costly lesson in the crucial importance of protecting...
U.S. Response to Coal Demand: Port and Harbor Improvements
The OPEC oil embargo, which caused long gasoline lines in 1973, caused incredibly long lines of coal ships along the East coast just last year. These ships came to bet coal to fuel overseas...
