Development of High Strength Composite Cables
Fiber reinforced composite materials offer significant advantages over conventional materials, for such factors as corrosion resistance, lighter weight, and higher strengths. These advantages...

Aerodynamic Improvements for Plate-Girder Bridges
This paper describes the application of wind tunnel tests on plate-girder cable-stayed bridges to ensure that the cross-section will not be susceptible to wind-induced oscillations. Information...

Retrofitting Aerodynamic Performance of Bridges
This paper is a review of aerodynamic retrofit techniques for long-span bridges. The discussion includes a description of the aerodynamic problems of static divergence, flutter, buffeting,...

Concrete Bridges — State-of-the-Art
The paper reviews the types of concrete bridge decks in most common use today, with particular emphasis on recent developments. Current trends in substructures and foundations are also...

Wind Resistant Design Manual for Highway Bridges
The new wind resistant design manual for highway bridges has been required recently in Japan. The working group was organized in the Japan Road Association is 1984 to prepare the manual....

Current Bridge Research at Iowa State University
For the past 20 years the majority of the structural engineering faculty in the Department of Civil and Construction Engineering at Iowa State University (ISU) have performed research...

Experimental Evaluation of Performance of Earthquake Restrainers in Box Girder Bridges
Type C-1 restrainers were used in most of the concrete T- and box girder bridges which have been retrofit. Type C-1 restrainers consist of 7-3/4 in. diam. galvanized cables, bearing plates,...

Recent Developments in Testing Base Isolation Systems
One of these developments has been the ability to test large scale isolation systems using simulated seismic loads. These tests have not only proven the performance and reliability of...

U.S. Navy's First Double Deck Pier, Post Construction

From Guesswork to Guarantee?
Maser describes a project to determine the effectiveness of radar and infrared thermography in detecting deterioration of asphalt overlaid bridge decks. The project, sponsored by the New...

Parking Garage Crisis
Corrosion in reinforced concrete parking garages is reaching crisis proportions. The rehabilitation market for these structures is estimated to be as much as $750 million a year, or 30%...

High-Strength Concrete: Weighing the Benefits
Russell, Gebler and Whiting describe the properties of high-strength concretes, the current state of knowledge on freeze/thaw effects, and procedures for batching, mixing, transporting,...

Classic Wood Structures
Wood has been used in a wide range of structural applications. When properly maintained, these structures can have a useful life from 50 years to several centuries. Thirty-seven unusual...
