Influence of Diaphragms on the Overall Performance of Bridges
Field data collected during vehicular loading has been used to evaluate the performance of diaphragms in composite steel plate girder bridges. This has included comparisons with finite...

NDE of Steel Bridges by Acoustic Emission
Acoustic emission technique (AE) was used to investigate fatigue cracking phenomenon during a series of laboratory tests of various bridge steels and during field testing of an in-service...

Proof Loads in LRFD Format for Bridge Evaluation
Proof load testing is considered as a reliable approach to evaluation of an existing structure's load-carrying capacity. It can be effectively used for highway bridge evaluation, to either...

Reliability of Highway Bridge Piers
Structural safety of reinforced concrete bridge piers supporting highway traffic is studied. Reliability indices for flexure, shear, and combined flexure and axial load limit states at...

After-Fracture Response of a Two-Girder Steel Bridge
The I-40 bridges over the Rio Grande are due to be razed in mid 1993 due to geometry and traffic safety considerations. The bridges are classified as 'fracture critical' two girder steel...

Full-Scale Bridge Test to Monitor Vibrational Signatures
A full-scale highway bridge, in the process of being demolished and replaced was monitored using vibrational techniques in its in-service condition. The bottom flange and web of one fascia...

Finite Element Analysis of a Highway Bridge Hinge
A highway bridge hinge is a very important element in bridge design. It releases thermal stresses that may be developed in the superstructure or the substructure of a bridge. A common...

Wood Bridge Design Using AASHTO LRFD Specifications
A nationwide project to develop a load and resistance factor (LRFD) design edition of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications...

Monitoring Performance of Full Scale Structures
General Physics Services Corporation (GPSC) of Columbia, Maryland has developed a device for the remote long-term monitoring of full scale structures, such as highway bridges. This patented...

Full Scale Dynamic Monitoring of Highway Bridges
Sensitivity of identified modal properties by physical testing is critical for automated monitoring of bridge structural condition. It is investigated here considering flexure modes and...

Geometric Design Projects for Highways
An Introduction
This book provides an introduction to geometric design of highways by means of examaples and projects that emphasize basic specifications, approaches to preliminary route selection, alignment,...

Recycled Roads
The movement to recycle wastes in highways appears to be gathering momentum nationwide. Rubber from old tires, wood chips, reclaimed asphalt pavement, fly ash, scrap plastic, mining wastes...

Marginal Overweight Operating Scenario for DOE's Initiative I Highway Casks
This paper assesses the potential transport of high-capacity Initiative I highway casks under development by the Office of Civilian Radioactive Waste Management (OCRWM) as permitted marginal...

Roadmapping: A Management Tool
Roadmapping is a process used by the U.S. Department of Energy (DOE) Office of Environmental Restoration and Waste Management (EM) to illustrate issue-based planning activities necessary...

Attitudes of the Knowledgeable Toward the Transportation of Spent Fuel
The purpose of the paper is to discuss the recent data analysis of a mail-in survey which investigated the attitudes of people having some knowledge of the nuclear industry. The survey...

Alternatives Analysis Using Two-Dimensional Modeling for the Owensboro Bridge and Approaches
The Federal Highway Administration plans to design and construct a new bridge over the Ohio River near Owensboro Kentucky. A hydraulic model with two-dimensional capabilities was utilized....

F. E. Everett Turnpike: An Application of MOSS
MOSS surface modeling software is being used successfully by Fay, Spofford & Thorndike, Inc., on a major project for the New Hampshire Department of Transportation to make improvements...

NOISE?A Comprehensive Software Library for Highway Noise Analysis
The Noise Software Library is a collection of highway noise analysis software tools that are arranged together under a powerful file management system which provides a transparent method...

The Application of AI in Highway CAD System
In a conventional CAD System, the process for solving a certain particular engineering problem is fixed stationary in the program. As a result, the program is often modified to fit different...

A Model to Quantify Work Space Availability for Space?Contrained Scheduling Within a CAD Environment
In any given process work area, a task or activity requires a specific amount of space for its execution. This required space must be accommodate by the physical space of the work area...
