Predicted Service Life of Armor Stone: A Case History
Laboratory testing for determination of true rock quality in terms of expected performance is not clear-cut, may be misleading, and requires extensive interpretation by an expert. This...
Geotechnical Aspects of Beach Restoration
Large-scale beach restoration undertaken by the U.S. Army Corps of Engineers in Florida requires millions of cubic yards of beach quality sand. Exploration for these sand resources starts...
Carolina Crossing
The designers of a cable-stayed bridge across the Cooper River in South Carolina incorporated stringent seismic criteria to safeguard against potentially devasting earthquakes....
Integration of Watershed and Ecological Site Land Classification Scales Using GIS Technology
Advanced analysis of hydrologic processes for use in natural resource simulation models and related applications including rangeland health assessments can be facilitated by the integration...
Better
A study of the professional literature indicates that the meaning of the term BMP, literally signifying a Best Management Practice, has diverged, depending on the professional field. Use...
Finding a Better Cover
An ongoing field test at Sandia National Laboratories, in Albuquerque, New Mexico, compares a basic soil and a compacted clay landfill cover currently prescribed by Environmental Protection...
Seismic Design of Highway Bridges: Recommended Specifications
Under the AASHTO-sponsored National Cooperative Highway Research Program (NCHRP), a joint venture of the Applied Technology Council and the Multidisciplinary Center for Earthquake Engineering...
A Framework for Performance-Based Seismic Design
The following probabilistic framework for seismic performance assessment is presented as an effective foundation for the development of performance-based guidelines. It suggests a generic...
Effect of Column-to-Beam Strength Ratio on Seismic Performance of RC Moment Frames
Reinforced concrete (RC) moment frames are often used in building applications. During strong earthquake excitations, such buildings have been subject to soft-story or column sidesway...
The Effect of the Slab on Beam-Column Joint Behavior
The three-dimensional effect of slab interaction on frame behavior has been observed in lateral load tests on beam-column-slab elements....
New Developments in the Field of Seismic Isolation
This paper will concentrate onwhat likely, is the most significant of these issues: changes in the mechanical properties ofseismic isolation and energy dissipation hardware as they are...
Performance of Masonry in Disasters: Lessons Learned and Research Needs Identified
This presentation described in this extended abstract is one of several in a panel discussion entitled Enhanced Research in Masonry. The objectives of the presentation are to discuss the...
Seismic Analysis and Retrofit of the Amoskeag Bridges
In 1983 AASHTO first offered the design guide for seismic analysis of bridges, which ultimately became a permanent part of the AASHTO Bridge Design Manual in 1990. Prior to this time,...
Rehabilitation of the Packers Falls Bridge
The Packers Falls Bridge was constructed in 1912 and consists of a 42' (12.8m) single span, reinforced concrete arch structure. This bridge was constructed using a unique forming system...

Civil Engineering Classics
Sponsored by the Geo-Institute of ASCE. This collections contains 35 key papers by James K. Mitchell during his extraordinary career as a geotechnical...
Geotechnical Testing, Observation, and Documentation
A geotechnical report, field and laboratory testing, as well as observation and documentation are all integral parts of most geotechnical projects. A technician is usually dispatched to...
Holding Steady
The San Diego�Coronado Bay Bridge is an unmistakable landmark that frames the skyline of downtown San Diego, providing a vital link between the mainland and the Coronado peninsula. The...
Competitive Edge
A new design system called the simplified economical bridge design (SEBD) makes steel cost-competitive with concrete for short- and medium-span bridges for the first time. In fact, a comparative...
