Economic Impact of Alternative Downtown UGM Strategies
In downtown Dallas, four strategies have been tested: consolidated public truck terminals; provision of off-street loading space in individual buildings, under ordinance; curb space management...
Load-Permit Truck Operations in New York State
This paper presents the results of a survey of indivisible-load permit vehicle operations in New York State. The survey was conducted in the context of an investigation into the impacts...
Truck Involvement in Fatal Urban Road Accidents in Australia
Trucks are over-represented (relative to vehicle numbers and vehicle-kilometers of travel) in fatal accidents. Those most at risk are occupants of other vehicles and pedestrians. Articulated...
A Method of Computing Impact and Fatigue Life in the Railway Steel Girder Bridge
The purpose of this paper is to investigate the dynamic interactions between an steel girder bridge and a moving freight train. A non-linear, 100-ton, freight car vehicle model and a 70-ft...
Retrofitting Aerodynamic Performance of Bridges
This paper is a review of aerodynamic retrofit techniques for long-span bridges. The discussion includes a description of the aerodynamic problems of static divergence, flutter, buffeting,...
Development of Skewed Element for the Concrete Pavements
In the recent years, highway engineers introduced skewed joints in the concrete pavement with a 4 foot to 5 foot skew on a 24 foot width pavement, which results in only one wheel crossing...
Guide for Evaluating Engineering Software
This is a practical guide to the problem of assessing the suitability of computer software being considered for use in engineering analysis, design or decision making. Each chapter treats...
Bullwinkle
The 1989 Outstanding Civil Engineering Achievement is an offshore oil production platform named Bullwinkle, a structure in the Gulf of Mexico that is taller than the Sears Tower, shaped...
Hydropower and Fish Passage Impacts
The Pacific Northwest Electric Power Planning and Conservation Act (Act) of 1980 formed the Northwest Power Planning Council, which establishes criteria and sets goals for developing future...
The Asbestos Agenda
Asbestos abatement business has been booming for years. The industry, though, is not restricted only to firms which do the removal. Companies who provide training, sell supplies and develop...
The Race for Smart Cars
Prendergast describes the technological elements involved in Intelligent Vehicle/Highway Systems (IVHS), current programs in Europe, Japan and the U.S. aimed at implementing IVHS systems,...
Resilient Moduli of Soils
Laboratory Conditions
Historically, structural pavement design has been based on static testing techniques, such as the CBR. More recently, the profession has placed increased emphasis on repeated load testing...
Accommodating Larger Trucks at At-Grade Intersections
When a particular intersection serves a high volume of large truck traffic, design considerations should reflect the presence of those larger vehicles. This paper discusses three intersection...
Analysis of Bridge Truck Loads
The development of the reliability-based load and resistance factor design (LRFD) methodology requires uncertainties in loads and resistance be quantified. In the load capacity evaluation...
Research Needs for Rational LRFD Criteria
There are at least a dozen factors causing or influencing impact. Current design specifications consider only a few of these. Location of truck wheel loads within the traffic lanes on...
Probabilistic Structural Response of a Turbopump Blade to Random Pulse Loading
The objective of this work is to develop probabilistic models of the response of a Space Shuttle Main Engine (SSME) turbopump blade to random impact loading. These loads are caused by...
Space Age Pueblo
If and when 8 million passengers decide to fly in and out of Albuquerque, N.M. in one year, the renovated and expanded airport will be ready for them. In a comprehensive $120 million project,...
A Study of Damage in Curved Composite Panels
Composite laminates subjected to a low speed impact, such as a dropped tool or a manufacturing load, often develop an internal delamination. This research studied the effects of a circular...
The Role of a Mobile Transporter in Large Space Structures Assembly and Maintenance
Large space structures require a vehicle to support assembly, operations, and maintenance. These vehicles may be designed for specific tasks or for general use throughout the life of the...
Changing Requirements
There are three sections to the presentation. First, a discussion of the changing environment of highway transportation - what are the factors and variables that are changing in the world...
