Tunnel Takes Cathodic Protection
Cathodic protection is nothing new for bridges and parking garages, but it has never been installed in a tunnel�until now. As part of a $15 million rehabilitation project, the method is...
Ohio Looks to Improve Bridge-Deck Performance
Caltrans to Retrofit Double-Deck Bridges
Design Cable-stayed Bridge for Cost Effectiveness and Safety
Innovative design approach is needed to enhance the prestigious status enjoyed by cable-stayed bridges. The present paper aims at such a goal of cost effectiveness and safety by providing...
Response of Suspension and Deck Arch Bridges to Spatially Varying Ground Motion
Recent awareness of the spatial variation of earthquake ground motion has caused concern about the safety of large engineered structures under seismic excitation. The effects of spatially...
Design and Construction of Waterfront Facilities at U.S. Navy Homeport at Ingleside, Texas
The waterfront facilities for the largest of the Navy's new homeports in the Gulf of Mexico were completed in 1990. The project included over 2,500 feet (762 m.) of deep draft bulkhead...
West Point Temporary Construction Dock
The West Point temporary construction dock is designed to provide construction access for the West Point treatment plant project located in Seattle, Washington. The dock plays a major...
Special Considerations for Railroads
In comparison with highway bridges, railroad bridges are generally characterized by a larger ratio between traffic and dead load, larger braking forces, smaller relative width of the bridge...
Optimum Design of Composite Bridge Deck Panels
Fiberglass and Graphite Cables for Bridge Decks
White Steel for Osaka Bay
Wind, earthquake and aesthetics were the design determinations for Japan's Higashi-Kobe Bridge. The designers also had to consider the man-made bay infill site and a directive...
Aluminum Bridge Decks are a Reality
Cables Not in Trouble
Cable-stayed bridges in the U.S. are not, contrary to reports widely disseminated in the press several years ago, about to fail from corrosion. The design, in which primary cables support...
Temporary Traffic Deck Over Braced Excavation
A case history is used to examine the planning, design, and installation of a temporary traffic deck over a 23-foot-deep braced excavation. The deck was installed in a three-phase sequence...
Double-Decking the Freeways
Elevated highways cost more than at-grade construction. Nonetheless, the hidden costs of increased traffic congestion and the real cost of urban right-of-way make elevated highways feasible....
Flawed Assumptions: Why Bridge Deck Joints Fail
Engineers should continually examine, evaluate and improve their representations of reality to avoid basing their beliefs, decisions, practices and policies on flawed assumptions. Such...
Plastic Highway Bridges
For highway bridges, composites are most effective in cables and decks. Researchers have developed and tested cables and deck sections for strength and fatigue resistance. Link-type cables...
Evaluation of Techniques for the Seismic Modeling of Elevated Freeway Bridges
Following the October 1989 Loma Prieta earthquake in Northern California, a number of seismic parametric studies were performed for both two-level elevated freeways and single-column bridge...
The Design and Construction Aspects of the Structure Research Tests at Cypress Viaduct
A research program is described whose task was to gather information about the inherent strengths and weaknesses of the existing Cypress bridge structure and to evaluate the effectiveness...
