Foias-Temam Approximations of Attractors for Galloping Oscillators
A method for the algebraic approximation of attractors recently developed by Foias and Temam is adapted for application to autonomous galloping oscillators. We compare results obtained...

Experimental and Numerical Chaos in Continuous Systems: Two Case Studies
Motivated by recent numerical investigations according to which certain types of deep-water compliant offshore structures may experience undesirable chaotic motions, two types of experimental...

Cumulants of the Nonlinear Combination of Independent Random Variables
A random variable of interest is often the sum of linear or nonlinear combinations of many independent random variables. In calculating the statistics of this random sum, advantages of...

Adequacy of Statistical Linearization for Nonlinear Degrading Structural Systems
An investigation is carried out to examine the validity of current practice in using statistical linearization method for nonlinear degrading structures subject to random ground acceleration....

Stability Analysis of Nonlinear Frames
The second stiffness method for large deformation in-elastic stability analysis of frames is discussed. Displacement control methods for tracing the path beyond the limit point are presented....

Damage Tolerance of Composites
The damage tolerance issue in composites is driven by the requirement for and implementation of a structural integrity criterion for a structural system. A key element in the design philosophy...

The Application of Computerized Tomography for Determining Material Properties
X-ray computerized tomography (CT) is an imaging technique that has been used by the medical community for a number of years and is well documented. However, the adaption of this technique...

Experimental Techniques to Study the Microstructure of Cement-Based Materials
Techniques to identify phases and changes in microstructure within cement paste, mortar, and concrete using a scanning electron microscope and image analysis system are described. Backscattered...

Nonlocality of Continuum Approximation of Microcracked Materials
A continuum with nonlocal damage has recently been shown to be an effective approach for the analysis of strain-softening structures. The basic idea is that only the damage, normally caused...

ASCE Annual Combined Index 1990
The 1990 ASCE Annual Combined Index provides a guide to material appearing in publications of the American Society of Civil Engineers published...

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...

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...

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...

GIS Risk Analysis of Hazardous Materials Transport
The Geographic Information System (GIS) was used to assess the risks and vulnerability of transporting hazardous materials and wastes on the Arizona highway system. This paper discusses...

Use of Advanced Technologies for Improving Hazmat Transportation Safety
This paper describes how advanced technologies can help improve the safety of over the road hazardous material transportation. The technologies discussed include driver information systems,...

Computer-Assisted Risk Assessment of Dangerous Goods Transportation for Haute-Normandie
To assess the 'best' routes for the transport of dangerous goods in an area of 600 km2 in France, software based on a geographical information system to manage,...
