Geosynthetics for Soil Improvement
Geosynthetics have had a tremendous impact on various aspects of soil improvement. In a number of situations which previously had not been technically or economically feasible, geosynthetics...
Analytical Studies of the Schoharie Bridge Failure
Analytical studies consisted of geomorphic, hydrologic, hydraulic, and erosion analyses including mathematical modeling with HEC-1 and WSPRO, the new FHWA water-surface profile model....
Schoharie Creek Bridge Model Study
On April 5, 1987, a major storm occurred in the Schoharie Creek watershed and the resulting flood caused the bridge to fail. The hydraulic model of the bridge was performed to simulate...
Mathematical Model of Wave Induced Pressures
A two-dimensional, implicit finite difference model was built to compute surface wave induced pressures under a gravity base foundation. The results showed considerable wave attenuation...
Composite Construction in Steel and Concrete
Composite steel-concrete systems are used extensively for buildings, bridges, and other civil engineering structures. Research and development related to composite construction are in...
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...
A New Lake and a Beautiful Bridge
The two 1988 OCEA awards of merit are the Great Salt Lake west desert pumping project and the Sunshine Skyway near Tampa, FL. Both projects were constructed fairly quickly. The pumping...
Ten Top Projects for 1988
The other Outstanding Civil Engineering Achievement nominees make up an impressive collection of projects. They are notable for innovative management techniques, state-of-the-art engineering...
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...
Guide for Design of Steel Transmission Towers
ASCE Manual 52,
The Eccentric Entrance
Architects design irregularly shaped buildings to give their clients something different, and this creates problems for structural engineers, especially in earthquake zones. The Brinderson...
Tied Arch Substitute
When the Minnesota DOT decided to build a new bridge to replace St. Paul's historic High Bridge over the Mississippi, a citizen's advisory group insisted that...
The Williamsburg: Rehab After All
Whether to repair or replace the Williamsburg Bridge has been seriously debated in New York City for years. Recently, a blue ribbon panel of technical advisors appointed by the Mayor conducted...
Brighter Future for Stay Cables
Corrosion problems on cable stayed bridges can be prevented, according to several engineers who responsed to Cables in Trouble, a Civil Engineering article that appeared in the April 1988...
Weathering Steel: Industry's Stepchild
Improper location and poor detailing are two reasons why some weathering steel bridges are not living up to their early promise. That was the consensus reached during a July 1988 forum...
Recycling Bridges
Faced with the statistics showing that more than half of our bridges have fallen into a state of disrepair, bridge engineers have coined a phrase from the lexicon of conservationists to...
Program to Reduce Deicing Chemical Usage
Over the years (since about 1948), the dependency on deicing chemicals has been increased to provide 'bare pavement' for safe and efficient winter transportation....
AASHTO Design Concepts
The AASHO Road Test of 1958-60 grew out of a need to quantify the effects of increasingly heavier axle and gross loads and varying wheel load configurations on the performance of this...
What Will Happen to Local Rural Roads and Bridges
Much of the local rural road and bridge system was not designed for the heavy trucks and farm equipment that are currently using the system. The system will continue to deteriorate unless...
Should Fast Track be Derailed?
Engineers, architects and owners believe that fast track construction is a great idea when it works, but serious problems can arise. Some engineers feel that the owner reaps all the benefits...
