1991 OCEA Award Nominees
The $1.2 billion I-595/Port Everglades Expressway runs from Port Everglades to I-75, giving traffic a much quicker route from the Miami area to the Gulf Coast. It also links U.S. 1, I-95,...
A Decade of Recovery
The Outstanding Civil Engineering Achievement Award for 1991 went not to a single project, but to an entire decade's effort by the Portland (Ore.) District of the U.S. Army...
A New Look at Galvanized Bridges
Engineers are rediscovering that galvanizing is one of the longest lasting methods of imparting corrosion protection to steel bridges. It also avoids the stringent new EPA regulations...
Out of the Lab...and into the Field?
Materials experts know very little about concrete's basic structure. Now, though, engineers at a research center sponsored by the National Science Foundation are working on...
Every Penny's Worth
Value engineering has been used in the construction industry since the 1960s, but highway projects have sometimes been thought of as too simple for VE studies. Now, with the increasing...
Seismic Design and Performance of Railroad Bridges
Damage to railroad bridges during earthquakes in the United States and Japan is summarized. Research tasks are outlined to develop seismic design and retrofit criteria for railroad bridges....
Seismic Design for Port of Los Angeles, 2020 Program
Due to the Port of Los Angeles' (POLA) importance as a regional hub for transportation and commerce and the potential for a major seismic event in the Southern California...
Seismic Practices for the Air Transportation System: Evolution and Needs
The seismic performance of air transportation systems is reviewed. The evolution of seismic design criteria and practices for major air transportation system elements is discussed. The...
Regional Risk Assessment of Environmental Contamination from Oil Pipelines
This paper presents a methodology for assessing the risk of environmental contamination from oil pipeline leaks due to earthquakes. Risk is measured both as volume of oil released and...
Design of Substation Foundations for Liquefaction
When substation foundations penetrate liquefiable strata within risk prone seismic regions, the potential loss of support must be evaluated with state-of-the-art methods to determine foundation...
Investigating Fault Rupture Hazards: An Example from the Wasatch Fault Zone, Utah
The Kern River project consists of a 36-inch diameter high-pressure natural gas pipeline, to be constructed from southwestern Wyoming to southern California. The alignment crosses several...
Seismic Hazard Analysis of Buried Pipeline for Design
This paper concerns mainly the following three items on seismic hazard analysis of buried pipeline for design: (1) effects of pipeline length on risk, (2) effects of local site conditions...
Wellington's Lifelines in Earthquake Project: An Outline of a Major Review
This paper outlines a project involving a major review of all lifelines including building services in the region of Wellington, New Zealand. A case study approach was used involving representatives...
A Methodology for Assessing the Risk of Hazardous Materials Release Following Earthquakes?A Demonstration Study for the Los Angeles Area
A methodology for estimating the risk of post-earthquake hazardous materials releases was developed for the National Science Foundation and the National Center for Earthquake Engineering...
Seismic Vulnerability Assessment of Bridges on Earthquake Priority Routes in Western Kentucky
This paper discusses the current conditions of 203 bridges on the priority routes in Western Kentucky and their vulnerabilities to earthquakes. A span-loss type of bridge collapse due...
Evaluation of Automatic Earthquake Shutoff Valve Performance and Recommendations for Future U.S. Standards
Increasing interest of local and state government has developed in recent years regarding legislation requiring automatic shutoff valves for natural gas lines as well as lines containing...
Post Earthquake Investigation Team
The CALTRANS Post Earthquake Investigation Team (PEQIT) has been in existence since 1971. It is an emergency response team which mobilizes quickly following a major earthquake to gather...
Engineering Tactics on Lifelines Safety Against Earthquakes
Effects of sediment-filled valley on seismic ground motions have become of major interest in earthquake engineering throughout this decade. This paper presents interesting phenomena of...
Measuring Section-Related Traffic Data by Correlation Methods?A New Approach to Traffic Monitoring and Control
Traffic monitoring and control systems require reliable realtime data on traffic flow for an efficient performance. A new 'class' of data, the so-called section-related data such as journey...
