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...
Structural Lumber from Small-Diameter Western U.S. Softwood Trees
The purpose of this study was to determine the mechanical properties, and corresponding economic value, of dimension lumber produced from selected over-stocked forest stands of small-diameter...
Big Screen Debut
The Glenn-Colusa Irrigation District (GCID) encompasses nearly 150,000 acres (60,700 ha) of prime agricultural land in California's Sacramento Valley, generally considered...
Dam within a Dam
A routine inspection of the Rock Run Dam, an 84-year-old Ambursen-type structure in Chester County, Pennsylvania, revealed major stress cracks and water stains on the inside face of the...
Deep Foundations In the Future (Available in Geo-Environmental Special Issue only)
The design and construction of deep foundations has gone from an art form to a scientifically based engineering practice. Research in this field has improved over the past century and...
Three Dams, One Reservoir
The three dams that make up the 800,000 acre-ft (987 million m�) Eastside Reservoir in Riverside County, California, required extensive foundation excavation and careful placement of embankment...
Beyond Convention
As engineers approach the design of new and expanded convention centers around the country, they must consider not only the changing needs of convention-goers, but also the surrounding...
Sum of the Parts
As with all of the bay bridges that serve as life lines to the San Francisco peninsula, the 32-year-old San Mateo Bridge needs strengthening to withstand a maximum credible earthquake...
Scenic-Bridge Strengthening (Available in Structural Engineering Special Issue only)
Built in 1937, California's Big Creek Bridge�a double-arch crossing with half-arch side spans�was due for a seismic retrofit. Challenged by the structure's unique...
Suspension Solution
The new bridge across the Carquinez Strait near San Francisco, California, will upgrade an important transportation link across the Sacramento River. This new bridge, which renders the...
Testing the Load (Available in Geoenvironmental Engineering Special Issue only)
The Pittsburgh District of the U.S. Army Corps of Engineers recently began construction of a new gated dam to replace a nearly 100-year-old concrete fixed-crest dam on the Monongahela...
Monitoring the Fresh Kills Landfill (Available in the Geoenvironmental Special Section only)
A unique system has been developed to assess the stability of the Fresh Kills Landfill, in New York City, using more than 260 geotechnical instruments and automatic processes. The system...
Blocking the Tide
The city of Venice is in peril as a result of increased tidal flooding, and a proposed system of movable gates offers the greatest promise of safeguarding the city's future....
Guidelines for Instrumentation and Measurements for Monitoring Dam Performance
Prepared by the Task Committee on Instrumentation and Monitoring Dam Performance of the Hydropower Committee of the Energy Division of ASCE. This report...
Foundation Design for the Elevated Station
The Amundsen-Scott South Pole Station is located at an elevation of 2,850 m on the 3,200 m thick polar plateau, a field of ice and snow that is moving toward the ocean at a rate of 10...

Sizing Up Seismic Bearings
Today in the U.S., there are two general technologies available to protect new and existing bridges from the damaging effects of earthquakes. One type, seismic isolation bearings, provide...
Catch the Wind
Wind turbines can now produce energy that is cost-competitive with other, more conventional power generation methods. The increased efficiency is due in part to the turbines'...
For the Duration
The U.S. Army Corps of Engineers developed a new grouting method called duration grouting when constructing the foundations for the Portugues Dam in Ponce, Puerto Rico. The site is marked...
Construction Control for Earth and Rockfill Dams
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 27 This manual provides critical guidance for constructors...
