Acceleration response records obtained during the October 17, 1989 Loma Prieta earthquake [Ms = 7.1] from the 47-story, eccentrically braced Embarcadero...

Remote Monitoring of a Stressed Timber Bridge Deck
The long term behavior of a CCA treated stressed timber deck bridge is being monitored, at present, using a remote data acquisition system. The bridge which is located in Gray, Maine was...

Structural Analysis in Context
The issues of what student should learn about structural analysis and how it should be taught are explored considering the purposes of structural analysis in engineering practice and the...

Design Considerations for Raising Existing Dams for Increased Storage
While a number of new dams have been constructed in the United States and other countries in recent years, much of the construction activity related to dams has involved the raising of...

Certified Safety Assessment of Zoccolo Dam
The paper reports one of the activities carried out in the framework of a so called `certified assessment of safety' program activated by ENEL SpA - Italian National Electric Board - in...

The Causticity of Accelerator for Shotcrete and its Impairment on Strength of Shotcrete
How on earth is the toxic and caustic injury of accelerator for shotcrete to operators and animals? How about its impairment on strength of shotcrete? The paper gives some reports and...

IVHS: The Invisible Revolution
Federal funding for intelligent vehicle highway systems has increased a hundredfold since 1989, from $2 million to almost $200 million. Transportation planners are looking increasingly...

Recycled Roads
The movement to recycle wastes in highways appears to be gathering momentum nationwide. Rubber from old tires, wood chips, reclaimed asphalt pavement, fly ash, scrap plastic, mining wastes...

Driving Under a Construction Site
Throughout the summer of 1992, vehicles passed unimpeded through one of the most heavily traveled intersections in Los Angeles County as construction proceeded on a concrete light-rail...

Predicting Pollution
For urban areas struggling to meet the requirements of the 1990 Clean Air Act as well as state air-quality mandates, accurate forecasting of mobile emissions is critical to evaluating...

Preliminary Assessment of Fault Rupture Hazard at the Yucca Mountain Site Based on Expert Judgement
The judgments of seven earth science experts were elicited to quantify the uncertainties associated with the likelihood of fault displacement through the proposed repository at Yucca Mountain...

Marginal Overweight Operating Scenario for DOE's Initiative I Highway Casks
This paper assesses the potential transport of high-capacity Initiative I highway casks under development by the Office of Civilian Radioactive Waste Management (OCRWM) as permitted marginal...

A Job Performance Aid to Criticality Safety
The handling of hazardous materials is becoming more and more of a major concern to everyone. As a result the laws and restrictions regulating the handling, storage, disposal etc., of...

Using Co-Management in a Voluntary Hazardous Waste Facility Siting Process
The recent approval for construction and operation of a hazardous waste management facility in Manitoba, Canada is an example of a siting process that is voluntary and that gives the community...

Effect of the Periodic Secondary Irregularity on the Dynamic Behaviour of Railway Bridge-Vehicle System
The deformation and vibration of bridge will be developed due to the moving vehicles, especially for railway bridge. The dynamic deflections in the points under each wheel are called secondary...

Safety of Passengers on Railway Platforms?Using Various Computers
