State and Local Issues in Transportation of Hazardous Waste Materials
Towards a National Strategy
This proceedings contains papers presented at the specialty conference State and Local Issues in Transportation of Hazardous Materials: Towards a National Strategy held on May 14-16, 1990...
Future Fill-Up
The car rental agencies at Phoenix Sky Harbor Airport have combined their service/filling facilities in the new terminal's parking garage. This permits customers to pick up...
Air-Water Transfer: The Role of Partitioning
A review is presented of the role of air-water equilibrium in determining the direction and rate of transfer of chemicals between water bodies and the atmosphere. Because this diffusive...
Oxygen Transfer in Full Lift Hypolimnetic Aeration Systems
A series of experiments were conducted to examine the effect of diffuser depth, diffuser orifice diameter and separator box surface area on oxygen transfer (mg/L), daily oxygen load (kg...
Determination and Presentation of Subsurface Conditions for Design and Construction
A major problem in the design and construction of many engineering projects is the lack of adequate geotechnical information both for design and for determining conditions to be encountered...
Construction under Fire
Construction is not carried out in a laboratory setting under controlled conditions�especially in areas of socio-political conflict, such as El Salvador in the 1980s. Instead, the construction...
Engineering Women Into the Workplace
According to the U.S. Department of Labor, by the year 2000, only 15% of the work force will be white men; 64% will be women of mixed ethnic backgrounds. Clearly, statistics show that...
Flawed Assumptions: Why Bridge Deck Joints Fail
Engineers should continually examine, evaluate and improve their representations of reality to avoid basing their beliefs, decisions, practices and policies on flawed assumptions. Such...
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...
Recent Advances in Seismic Design and Retrofit of California Bridges
This paper describes the damage and lessons learned from the most recent major earthquakes, the resulting bridge seismic design and detailing changes and the seismic retrofit program implemented...
Seismic Design and Performance of Railroad Bridges
Damage to railroad bridges during earthquakes in the United States and Japan is summarized. Research tasks are outlined to develop seismic design and retrofit criteria for railroad bridges....
Earthquake Considerations in Design of the Los Angeles Metro
This paper discusses the earthquake design of the Los Angeles Metro. The design earthquake parameters are presented and discussed in light of the behavior of buried structures subjected...
Seismic Practices for the Air Transportation System: Evolution and Needs
The seismic performance of air transportation systems is reviewed. The evolution of seismic design criteria and practices for major air transportation system elements is discussed. The...
San Francisco Double-Deck Viaduct Retrofits
Following the Loma Prieta Earthquake in October 1989, six double-deck reinforced concrete viaducts in San Francisco were closed because of some isolated damage, and as a precaution for...
Retrofitting Northwest Connector for Seismic Forces
Many pre-1971 bridges in California have inadequate seismic resistance due to non-ductile components or poor connectivity of superstructure elements. Caltrans has finished the first retrofit...
Lifeline Design of Bridges
An analysis and design procedure is presented for retrofitting steel girder bridges that may experience the loss of a pier or column. Multispan and continuous grider bridges are treated....
Scenario for Improving the Seismic Resistance of Pipelines in the Central United States
A number of pipelines transporting crude oil and natural gas to the Midwest and Northeast pass within and adjacent to the New Madrid seismic zone in the central United States. A major...
Telecommunications Facilities Earthquake Readiness Since San Fernando
The vertical rack architecture of telecommunication offices showed some weaknesses during the San Fernando earthquake in 1970. Efforts have been made since then to improve performance...
Economic Impact of Earthquake Effects on the City of Everett's Lifelines
The economic effects of lifelines failures, caused by three hypothesized earthquake scenarios, in the city of Everett, Washington are estimated. The project team consists of lifeline seismic...
