The Strategic Exploration Initiative - Lunar Basing
The Strategic Exploration Initiative (SEI), as conceived by the author in 1987, applies the weaponry of the Strategic Defense Initiative (SDI) to non-military goals. These include directed...
Plasma Reactor Waste Management Systems
The University of North Dakota is developing a plasma reactor system for use in closed-loop processing which includes biological, materials, manufacturing, and waste processing. Direct-current,...
Nature's Solutions to Space Insulation
Humans working or living in the harsh environment in space must be protected from temperature extremes. Any effective insulating system must be able to withstand a wide range of temperatures....
Oxygen Production for a Future Lunar Base
This paper discusses various ways for providing oxygen for a lunar base. Currently, there are three methods available which are technologically possible. One of these is the use of chemical...
Sulfur-Based Construction Materials for Lunar Construction
Several approaches have been suggested to use lunar or Martian aggregate in extraterrestrial construction. These approaches include hot pressing of lunar soils producing cements and concretes...
Composite Construction in Steel and Concrete
Composite steel-concrete systems are used extensively for buildings, bridges, and other civil engineering structures. Research and development related to composite construction are in...
Earthquake Engineering and Soil Dynamics II?Recent Advances in Ground-Motion Evaluation
Ground-motion determination for analysis and design of engineering structures is a shared, interdisciplinary task involving geologists, seismologists, geophysicists, geotechnical engineers,...
Waste Processing: Makes Good Energy
Materials separation in solid wastes streams will generate more BTU's at waste-to-energy facilities. The removal of noncombustibles like bottles, batteries and refrigerators...
Life-Safety, Key to Seismic Evaluation
Most buildings in the U.S. don't meet modern standards for withstanding potential damage from possible earthquakes, and existing buildings present one of the greatest risks...
Seismic Risk to Natural Gas and Oil Systems
This paper begins with a brief summary of significant earthquake damage to gas and oil lifeline systems during several earthquakes. Following this discussion, the objectives and major...
Seismic Reliability of Hierarchical Lifeline Systems
The problem to be considered here is the vulnerability and reliability of a functionally as well as physically hierarchical lifeline system. Most major lifeline systems have this feature;...
Mitigation of Seismic Effects on Water Systems
Historically, earthquakes have caused damage to water systems. In this paper, water system facilities at risk due to seismic activity as well as potential damage mechanisms are identified....
Seismic Damage and Retrofit of Bridges in California
Since 1971, the California Department of Transportation (CALTRANS) has retrofitted about 1300 bridges to improve their seismic resistance. CALTRANS has investigated 13 earthquakes since...
Sylmar HVDC Converter Station East Seismic Design
The Sylmar Converter Station East in Los Angeles receives power from the Northwest via the Pacific HVDC Intertie, a ?500 kV dc transmission line. At Sylmar, the energy is converted to...
Hydraulic Fill Structures
This volume contains 53 papers covering many aspects of hydraulic fill structures with special emphasis on geotechnical issues. The papers present an excellent review of historical development,...
Designng to a Fault
Engineers designed a $30 million expansion of one of the Port of Los Angeles' busiest shipping terminals for a site sitting over the Palos Verdes Fault. Because closing the...
New Found Youth for an Old Foundry
The Grey Iron plant, central foundry division of General Motors Corp., in Saginaw, Mich. conducted a study to evaluate the capacity and tooling of future casting operations of the more...
Massive Resistance
The recently completed structural reinforcement of the 95 year old landmark Salt Lake City & County building, and its 250 ft high central clocktower, is believed to be the first...
Epoxy Update
Epoxy-coated reinforcing steel protects against corrosion if it is used correctly. Several construction practices, such as prescribing the limits on permissible coating damage due to shipping...
Leakproofing an RCC dam
