Design of an Expert System for the Rating of Highway Bridges
A microcomputer-based expert system used to determine the effects of vehicles and overloaded vehicles on simple span bridges with reinforced concrete deck and prestressed concrete I-beams...
An Expert System for Inactive Hazardous Waste Site Characterization
The area of hazardous waste management is a broad and multidisciplinary field requiring expertise in engineering, geology, chemistry and toxicology, and is an ideal area for the application...
In-House Training in the Corps of Engineers
The Corps of Engineers is very active in the training of its employees and the results of training are the growth and professionalism of the employees. Supervisors must always develop...
Enhancing Highway Safety Through 3R Construction
The safety improvement programs specifically aimed at correcting high accident locations (HALs) are certainly helpful. These programs have resulted in sizeable frequency as well as severity...
Assessment of Safety Impacts of Highway Projects
In this paper the safety impact of highway improvement and maintenance activities is examined in terms of accident reduction potentials of these activities. There are three causes of accident:...
Treatment in Your Own Backyard
Everyone wants the nation's hazardous waste sites cleaned up, but nobody wants the wastes disposed of near them. Therefore, cleaning up these problems at the site may be the...
Risk Assessment: Engineering Tool
In factoring in human-health impacts when tackling an environmental problem, risk assessment is often the best approach. Its use is growing fast. The technique increasingly is being used...
Cladding Design for Tall Buildings
In the past twenty years, glass cladding has emerged as a popular and economic building material. Its use in tall buildings which are constructed in high-risk wind and seismic geographical...
Damping in Tall Buildings: Its Variability and Treatment in Design
Increasingly, damping is being recognized as an important factor in the design of structures. It is at the same time a property which is relatively poorly defined, more acquired than engineered...
Damping Systems to Limit the Motion of Tall Buildings
Two types of damping systems have been used successfully in building applications - the Tuned Mass Damper, and Viscoelastic Damping Units. In the past, Tuned Mass Dampers were used in...
Design of Viscoelastic Dampers for Columbia Center Building
To reduce the dynamic response of a building with a given height and plan area to wind load, aside from inherent damping of the building, the designer has a few options available to him/her....
Soil Quality Testing in Ports: Why?
The Port of Seattle has instituted an agency-wide environmental protection guidelines which include the option to prepare site histories and perform chemical screening of soils prior to...
Expert Systems in Civil Engineering
The importance of expert systems, also referred to as knowledge based expert systems, has been growing in all areas of civil engineering practice. The papers in this book were presented...
Building Motion in Wind
The trend towards higher structural efficiency and hence lower cost has resulted in a generation of lighter and more flexible buildings with a lower inherent capacity for energy dissipation...
The Mile High Dream
For the 1986 Tall Buildings Conference in Chicago, a group of experts studied the implications of a mile high skyscraper to be built of concrete. It is 500 ft square at the base, designed...
Expert Systems Enter the Marketplace
Civil engineering expert systems (computer programs that incorporate some of the decision-making capabilities of the top experts in a given subdiscipline) are beginning to come on the...
A Modern Cone Penetration Testing Vehicle
The geotechnical group at the University of Florida recently purchased a new insitu testing cone truck. This is a powerful, all wheel drive, off-the-road vehicle designed specially for...
Taming Lively Buildings
Mechanical damping systems are increasingly being used for controlling dynamic responses of tall buildings. Several types of dampers are described, and compared, beginning with the three...
A Field Study of Water Movement Through Clay Liners
A monitoring system has been designed for the field verification of a numerical model of water movement through the cover clay liner of hazardous waste landfills. The most unique aspect...
Effects of Organic Compounds on the Adsorption and Desorption of Metals in Soils
This study evaluated the adsorption and release rates of toxic metals in a soil system also impacted with organic compounds. The soil type studied is common to hazardous waste sites throughout...
