Failure Modes in Concrete Structures Due to Ice Load
Analytical methods are described for predicting local behavior of deepwater concrete structures subjected to short duration loading from floating ice. Overall analytical approaches such...
Spalling and Buckling of Ice Sheets
The effect of local eccentricity in the vertical direction on the magnitude of compressive strength of wide ice sheets is studied theoretically. Two new failure modes are identified: indentation...
Detection of Leakage Through Subsurface Barriers Using Guided Acoustic Waves
The primary method for preventing hazardous liquid and leachates from entering the groundwater is the use of a physical barrier. These barriers are susceptible to a number of mechanisms...
Automated People Movers?The Need for Flexibility and Clarity
The Airtrans System at Dallas/Ft. Worth Airport is the best example available of how an automated people mover (APM) might function in an urban setting. An examination of Airtrans shows...
Advances in High Strength Concrete,
The technology for producing field placeable concrete with a 28 day compressive strength of 10,000 psi has been available for many years. With the recent use of microsilica as an additive...
Regional Planning Models Used in Subarea Windows
The typical regional travel-forecasting model has historically been confined to use on a mainframe computer. In an effort to reduce costs and allow computer hardware options, a three-tiered...
Use of a Simplified Urban Traffic Forecasting Procedure for Project Analysis
This paper presents New York State Department of Transportation's experience with the calibration and testing of a simplified procedure for estimating urban traffic at the...
Modeling Techniques for Seismic Analysis of Supported Systems
An automated seismic qualification process is presented which integrates the modeling and evaluation aspects of supported system design. Emphasis is placed on baseplate and joint design....
A New Panama Canal?
The Panama Canal is expected to be obsolete by the end of the century. Already there are serious problems with ship traffic through the Canal: volume of traffic is down, average transit...
Policy Analysis Implications of Four Cogent Transportation Topics
Using a goal-group policy-analysis scheme and from his experience on Capitol Hill, the author documents his observations on the cogent transportation topics facing the United States in...
What Future for America's Railroads?
The public sees America's railroads as old, rundown, bankrupt and unreliable. However, after decades of decline, the rate of return on investments has begun to show a steady...
Intercity Bridge: First Major U.S. Cable-Stayed Bridge
The Intercity Bridge spans the Columbia River, connecting the cities of Pasco and Kennewick, Wash. It is the longest cable-stayed, concrete bridge in the U.S. (2,403-ft) and it has been...
Urban Freeways and Changing Social Values
One key reason for undertaking the $90 billion Interstate Highway System �even though the name may not so indicate? was traffic congestion in and near cities. The intercity segments of...
Urban Transportation Planning
Sources of Information on Urban Transportation
This book is a review of the procedures followed in the comprehensive urban transportation planning process including a history of its development, trip generation, trip distribution methods,...
