A Decision Support System for Water Supply Costing
Accurate cost estimates for water supply system expansions are an important component of the planning process. A spreadsheet-based cost estimating model called SWFCOST was developed as...
Diastolic Function Using 3-D Echo Reconstruction and Finite Element Analysis: Applications for Study in Animal Models and Patients
We have initiated animal experiments using three-dimensional reconstruction of echocardiographic recordings and finite element analysis to evaluate the effects of alterations in preload,...
Effects on Seismic Spatial Variations to Suspension Bridge Responses
The dynamic soil-structure interaction effects and spatial variations of a seismic motion seem to have significant contributions on the response evaluation of a long span suspension bridge....
A Second Order Analysis Technique for Nonprismatic Bridge Piers
An approximate second order method is presented for the analysis and design of cantilever compression members. Prismatic members with nonconstant reinforcement, and nonprismatic members...
Testing the Limits
More than 100,000 bridges in the U.S. are considered structurally deficient and in need of posted load limits or repair. As the number continues to mount, engineers search for a better...
Inspection Goes High Tech
Many believe that rehabilitation of the existing infrastructure�not net construction�will dominate the 1990s. Therefore, accurate condition assessment is crucial, since public works agencies...
Computer-Monitored Grouting
With grouting operations going on at many locations around the clock on a typical large dam-foundation project, how do you make sure that the designed mix is always being used and as-built...
Cables Not in Trouble
Cable-stayed bridges in the U.S. are not, contrary to reports widely disseminated in the press several years ago, about to fail from corrosion. The design, in which primary cables support...
State Legislative Concerns Relative to Federal Hazardous Materials Transportation Regulation
States have increasingly asserted their authority to regulate hazardous materials transportation, in the face of inadequate and declining federal efforts. Areas of state interest include...
Dangerous Goods Emergency Response?The Western Australian Experience
A general overview of the State of Western Australia including: the legal framework of the Dangerous Goods and Emergency response management scenarios; particular problems unique to the...
Risk Management in the Transportation of Dangerous Goods?The Influence of Public Perception A Discussion
In 1988, a fire at Saint-Basile-le-Grand, Quebec involving a PCB (polychlorinated biphenyls) warehouse sparked continuing controversy which included a two-week evacuation of residents....
Developing High-Risk Scenarios and Countermeasure Ideas for Mitigation of Hazardous Materials Incidents
Kansas State University (KSU) conducted a comprehensive study of the development of a set of prioritized, extreme-risk scenarios, the development of a set of feasible, practical and implementable...
Risk Perception and Policy Preferences of Fire Chiefs: A Survey of Hazardous Materials Issues
This paper presents the results of a survey of Connecticut fire chiefs and discusses how their perceptions of risk affect their attitudes towards risk preparedness and risk management...
Hazardous Materials Data: A Federal Perspective
This paper discusses the evolution and current status of the Hazardous Materials Incident Report System (HMIRS) maintained by the Research and Special Programs Administration (RSPA) of...
Flows of Hazardous Materials Through States by Rail
This paper presents information on the tonnages of hazardous materials passing through each of the contiguous 48 states (and the District of Columbia) by rail. The quantities are estimated...
Issues in Developing Arizona's Hazmat Incident Reporting Program
The Arizona Division of Emergency Services (ADES), in cooperation with Arizona State University (ASU) - Center for Advanced Research in Transportation, and the Arizona Department of Transportation...
Developing a HazMat Incident Evaluation Program
This paper describes the Illinois Hazardous Materials Incident Evaluation Program. The history, development strategies, implementation, forms for reporting, screening and data input, and...
Canadian Database Development as a Support Tool to Transport Risk Assessment
The Risk Management Branch of the Transport Dangerous Goods Directorate supports a multi-modal safety program for dangerous goods transportation through the measurement, assessment and...
Managing Risks of Hazardous Materials Transportation in Santa Barbara County
This paper presents some potential building blocks which local jurisdictions can pursue to manage the risks associated with hazardous materials transportation (HMT). The recent experience...
Assessing Community Safety for Hazardous Materials Transport
This paper describes a computer model developed to assess the safety of a community through which hazardous materials will be transported. The model is predictive and can be used even...
