Expert System for Risk Assessment of Concrete Dams
An expert system is presented that will assist a field inspector, during the site investigation of an existing concrete dam, to perform a preliminary structural risk assessment of the...
Practice of Risk Analysis in the Private Sector
Although risk-analysis is currently gaining acceptance in the decision process among engineers involved in public safety of water resources projects, the 'state-of-the-art'...
Evaluation and Upgrading of Wood Structures
Case Studies
The need to evaluate and upgrade existing wood structures stems from concerns of safety and serviceability. These concerns are caused for a variety of reasons which include plans for continued...
Housing and Hazardous Waste Contamination
Problems and Remedies
When hazardous waste sites are discovered in close proximity to residential areas, scientists and engineers are often faced with conducting complex studies involving many government agencies...
Defining the Infrastructure Problem?The Local View
The Governor's report defines infrastructure as 'the collective network of physical facilities and their maintenance necessary to sustain economic growth and...
Maintenance Levels of Service Guidelines
Maintenance levels of service define the threshold physical conditions that indicate a need for maintenance and repair activities and prescribe restored conditions after maintenance is...
Infrastructure: Rehabilitation or New
Basically, each public entity needs to inventory its infrastructure system and evaluate its importance to the immediate requirements of public health, safety and welfare. Prioritize the...
Rehabilitation of the CNW and ICG Railroads
The railroad industry is an indispensable part of the American economy. However, the railroad infrastructure was allowed to deteriorate to the extent of having 5. 4 billion in deferred...
Probabilistic Design of Gravity Foundations for Arctic Offshore Structures
The use of the probabilistic simulation technique to estimate the variability of the resistance and the ice load on arctic gravity structures is illustrated in order to assess the safety...
Structural Considerations for a Radwaste Facility
The structural engineer needs to consider several criteria when designing a radioactive-waste processing facility in order to properly balance the requirements of safety and economy. This...
Structural Retrofit for Nuclear Power Plants
Retrofitting of nuclear power plants is a major concern these days. Recent rulings of regulatory agencies have affected most of the generating plants in some way. The lessons learned from...
The 1984 novel
Finite Element Methods in Structural Safety Studies
The use of finite element methods in structural safety studies is discussed and recent work in the area is briefly reviewed. Formulation for a first-order stochastic finite element method...
Installation of Category I Caissons
Founding a proposed safety-related Category I structure of a nuclear power plant on rock socketed caissons necessitated using precision installation techniques. These techniques were chosen...
Assessing Seepage at Uncontrolled Hazardous Waste Sites
This paper presents a conceptual framework for estimating the concentration of organic contaminants in a groundwater plume over time. The basis of this framework is the application of...
Application of Displacement of Discontinuity Methods in Underground Mine Design
Displacement discontinuity methods for stress analysis, pioneered by Starfield and Crouch (see, for example, Starfield and Crouch, 1972; Crouch, 1976; and Crouch and Starfield, 1983),...
Noise Assessment, Measurement, and Mitigation, an OSHA View
A discussion is presented on the Occupational Safety and Health Administration (OSHA) 29 CFR 1910. 95 General Industry noise exposure standards and the 29 CFR 1926. 52 and 1926. 101 Construction...
Monitoring Saves a Site
A comparison is made of two supported excavations that were similarly designed and constructed. Both excavation support systems consisted of a soldier pile and lagging sheeting wall supported...
Methodology of Determining Acceptable Levels of Heavy Metal Contamination in Municipal Sewage Sludge Applied to Cropland
The potential public health risks associated with the agricultural utilization of municipal sewage sludge dictate the development of environmentally acceptable criteria for the disposal...
Characterization of Indoor Carbon Monoxide Levels Produced by the Automobile
