Earthquake Engineering and Soil Dynamics II?Recent Advances in Ground-Motion Evaluation
Ground-motion determination for analysis and design of engineering structures is a shared, interdisciplinary task involving geologists, seismologists, geophysicists, geotechnical engineers,...
Affordable CADD
In the past few years many civil engineers have become aware of the advantages of CADD systems. However, CADD systems were originally prohibitively expensive for all but the largest offices....
Keeping Tabs on CADD
In 1983 Howard Needles Tammen and Bergendoff (HNTB) began to implement a CADD system. Fostering the independence of individual offices while maintaining the company wide standards and...
Transit Triumph
The 1988 Outstanding Civil Engineering Achievement is Boston's Southwest Corridor, chosen not only for its size, complexity and technology, but for its environmental, public...
Life-Safety, Key to Seismic Evaluation
Most buildings in the U.S. don't meet modern standards for withstanding potential damage from possible earthquakes, and existing buildings present one of the greatest risks...
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...
The Federal Budgetary Process
The paper outlines the federal budget process as it affects highway safety programs. There are a variety of federal programs which come under the umbrella designation highway safety. Those...
Comparing Benefits of Safety and Non-Safety Programs
The objective of this presentation is to compare benefit-cost ratios for major highway construction projects to those for highway safety projects, such as: (1) new highways, (2) major...
A Case for Science-Based Road Safety Design and Management
What civil engineers do has a major effect on road safety. However, contrary to appearances, the level of safety built into roads is largely unpremeditated. Standards and practices have...
Highway Safety - Planning for the Future
Because motor vehicle traffic is expected to continue to grow, renewed efforts will be required to prevent the problem of motor vehicle crash deaths and injuries growing much larger than...
Plans and Programming for Highway Safety to the Year 2010
Many factors have contributed to improvement in highway safety including more crashworthy vehicle design, increased usage of occupant restraints, growing public intolerance of DWI, and...
Simulation of Long Period Ground Motions for a Large New Madrid Earthquake
Ground motions for a large New Madrid earthquake are simulated to provide response spectra in the period range of 0.5-20 seconds for hard rock sites at Chicago and Atlanta. The ground...
Seismic Risk to Natural Gas and Oil Systems
This paper begins with a brief summary of significant earthquake damage to gas and oil lifeline systems during several earthquakes. Following this discussion, the objectives and major...
Seismic Reliability of Hierarchical Lifeline Systems
The problem to be considered here is the vulnerability and reliability of a functionally as well as physically hierarchical lifeline system. Most major lifeline systems have this feature;...
Mitigation of Seismic Effects on Water Systems
Historically, earthquakes have caused damage to water systems. In this paper, water system facilities at risk due to seismic activity as well as potential damage mechanisms are identified....
Seismic Damage and Retrofit of Bridges in California
Since 1971, the California Department of Transportation (CALTRANS) has retrofitted about 1300 bridges to improve their seismic resistance. CALTRANS has investigated 13 earthquakes since...
Sylmar HVDC Converter Station East Seismic Design
The Sylmar Converter Station East in Los Angeles receives power from the Northwest via the Pacific HVDC Intertie, a ?500 kV dc transmission line. At Sylmar, the energy is converted to...
Elegant Interchange for Tight Urban Spaces
The Seventh St. underpass, which opened in May of 1987, is a multilevel uban interchange crossing I-10 in the center of Phoenix, Arizona. With little right of way available, the interchange...
