Cables Not in Trouble
Cable-stayed bridges in the U.S. are not, contrary to reports widely disseminated in the press several years ago, about to fail from corrosion. The design, in which primary cables support...

Lessons Learned by the News Media
The paper summarizes a few things learned from the news media's experience in Hurricane Hugo and which they will try to do differently the next time. These include: simulcasting...

Ferroresonance & the Snettisham Hydroelectric Project
Key system features of the Snettisham power plant in Alaska will be highlighted along with a discussion of the operational problems encountered due to a ferroresonant condition. The project...

1991 OCEA Award Nominees
The $1.2 billion I-595/Port Everglades Expressway runs from Port Everglades to I-75, giving traffic a much quicker route from the Miami area to the Gulf Coast. It also links U.S. 1, I-95,...

Plastic Highway Bridges
For highway bridges, composites are most effective in cables and decks. Researchers have developed and tested cables and deck sections for strength and fatigue resistance. Link-type cables...

Two Decades of Communications Systems Seismic Protection Improvements
Telecommunications systems in North America have gone through significant technology changes in the past twenty years. The electro-mechanical switching equipment has been replaced by electronic...

Hybrid Response Analysis of Buried Corrugated Pipeline Under Seismic Wave
Polyvinyl chloride and polyethylene corrugated pipes are recently used for buried water or sewer pipelines and also used as containers for electric cables. Seismic behavior of these pipelines...

Fiber Optic Communication Systems for Freeway Traffic Management
The communication requirements of freeway traffic management systems (FTMS) can be effectively met by systems which utilize fiber optic cables and associated equipment. This paper discusses...

Collision Risk Analysis Fixed Platform and Semisubmersible
This paper summarizes the North Sea experience pertaining to mooring line failures of conventional 8 and 12 anchor line systems. Mooring system calculations, experience and test results...

Reliability of Electric Power Transmission Systems in Seismically Active Metropolitan Tokyo: Part 1. Network Modeling
A method is proposed for modeling electric power transmission systems. The model can be used to evaluate the reliability of the network connectivity in a seismically active region. It...

Structural Error Identification for Control of Construction Accuracy
In cases of large-scaled structures it is very important to keep the criteria of construction accuracy and therefore to correct construction errors if any considerable errors are found...

Dynamic Stability of Cable Domes
The cable domes designed by David Geiger for the gymnastics and fencing arenas for the Olympics at Seoul, Korea, and for the stadium at St. Petersburg, Florida, are geometrically non-linear...

Safety Levels of Reinforced Concrete Box Culverts for Installing Power Supply Cables
The authors have examined the applicability of reliability-based design to the existing reinforced concrete box culverts for installing power supply cables. The lowest safety index of...

Research on Structural System Reliability of Cable-Stayed P.C. Railway Bridge Across Hong-Shui River
This paper analyses the structural system reliability of cable-stayed bridge by using the modified all failure modes. The concept of the structural subsystem is used to help the selection...

Fluid Line Deployment and Repair for Space Station
Deployment of the utility system for providing services to the NASA Space Station Freedom provides a unique challenge in design and material technology. The system must be lightweight,...

Translating Bridge Tolls to a New Bridge: The Third Dartford River Crossing
