The Demonstration Project on Seismic Loss Estimation for Water Systems
This year a monograph is being produced that summarizes results of a four-year project by the Technical Council on Lifeline Earthquake Engineering (TCLEE) of ASCE in order to demonstrate...
Effects of Uncertainties in Component Fragilities on Lifeline Seismic Risk Analysis
Accurate calculation of the seismic risk for lifelines requires modeling the system as a function of its components, and requires accurate modeling of two engineering factors: (1) the...
Seismic Risk Considerations for Transportation Systems
During the recent Loma Prieta Earthquake, major damage to certain key transportation elements greatly affected operations of major transportation systems within the San Francisco Bay Area....
Probabilistic Prediction of Losses to Lifeline Systems Due to Earthquakes
An efficient and practical method for earthquake loss estimation for lifelines is developed, using the recent advances made in the areas of lifeline earthquake engineering and probabilistic...
The U.S. Agency for International Development's Water and Sanitation for Health (WASH) Project: Lessons of the Decade
A review of the International Decade of Water Supply and Sanitation of the 1980's shows the enormous accomplishments made to date: 600 million more people served with a drinkable...
The International Drinking Water Supply and Sanitation Decade and Beyond
The International Drinking Water Supply and Sanitation Decade ends in 1990. Though the Decade has not achieved its numerical objective of universal access to water and sanitation, it has...
Advanced Integrated Wastewater Pond Systems
By incorporating special environments for methane fermentation and photosynthetic oxygenation, advanced integrated ponding systems attain high degrees of primary and secondary treatment...
Long-Term Water Supply and Demand in Light of California's Population Growth
Californians will have to be more creative, more imaginative, and willing to investigate new methods of meeting people's water needs. Waste water reclamation and water conservation...
Water Management During California's Drought
California is suffering from a fourth consecutive year of drought, and 1990 is shaping up to be the most severe of the four. Water planning in California is usually based upon the experience...
Cooperation: Solving the California Water Problem
The water picture in California is changing rapidly. Water professionals, to say nothing of the public at large, are hard-pressed to keep up with new technical information and changing...
Projects That Point
This is only a small sampling of what we can expect inthis decade. An $80 million kiln at Port Arthur, Tex., reportedly the largest of its kind in the U.S., handles bulk solids and sludges....
Do the Right Thing
Engineers and scientists at the Center for Advanced Decision Support for Water and Environmental Systems (CADSWES) are developing software to support water resource and environmental decision...
Anchoring a Dam
To comply with Federal Energy Regulatory Commission requirements with regard to stability under a postulated Probable Maximum Flood, an extensive foundation investigation and stability...
Recent Lifeline Seismic Risk Studies
This monograph is a collection of four papers presented at the 1990 Annual Civil Engineering Convention and Exposition in San Francisco, California. The papers summarize seismic loss and...
Building in Reservoirs
The Croton Supply System, one of the three major water supply systems for New York City, is undergoing extensive rehabilitation. In an innovative use of space, some of the new construction...
Commuter Control
Traffic management systems are a relatively new way to expand the capacity of existing highways and to utilize new ones realistically. Several major systems have been in place and new...
Haunches and Hangers
The $210 million VA Medical Center at Houston features a structural system as innovative for the 1990s as the interstitial space concept was in the 1960s. The medical center, designed...
An Education in Tunneling
A senior civil engineer and winner of the 1988 Martin Kapp Foundation Engineering Award describes the evolution of U.S. tunneling technology and practice. Trained as a structural engineer,...
Representation of Strategic Choices in Structural Modeling
A major concern in structural modeling is the proper choice of tools to achieve stated objectives. Problem statements in structural analysis and design are usually made in fairly abstract...
Experiments on Active Structural Control Under Seismic Loads
Two control systems, an active tendon system and an active mass damper system are selected for study for possible real structural implementation. Presented in this paper are simulation...
