Engineers are using the lightweight advantages of fiber reinforced polymers to build short span vehicular bridges and pedestrian bridges, particularly in remote areas, such as national...
Rapid Redecking
A contractor replaced nearly 7,000 m� of steel grid roadway deck filled with microsilica concrete on the Canadian crossing of the Thousand Islands bridge system more than one year ahead...
All Decked Out
After 50 years of wear, the deck of New York City's Williamsburg Bridge was buckling and badly in need of replacement. In 1994, consultants recommended replacing the deck...
Bridge Within a Bridge
A multinational consortium retrofitted the Tagus River suspension bridge in Lisbon, Portugal. The retrofit included widening the roadway deck from five to six lanes, installing a railroad...
Full Use of Arching in Deck Slabs (Available only in Structural Engineering Special Issue)
The use of arching concrete deck slabs allows engineers to safely reduce the amount of reinforcement at a significant overall cost savings. Engineers with the Ministry of Transportation...
Seismic in St. Louis
Following collapse of sections of the double-deck I-880 Cypress Viaduct in the 1989 Loma Prieta earthquake, the Missouri Department of Transportation initiated a seismic evaluation and...
Scandinavia's International Connection (Available only in Structural Engineering Special Issue)
The 7.8-km-long cable-stayed �resund Bridge, the centerpiece of the first road and rail link between Scandinavia and Europe, is the third and final link of the 15.8 km Oresund Link. The...
Tappan Zee Set for Inverset (Available only in
Replacing the deck on New York's Tappan Zee Bridge is a ticklish problem, considering that all of the work has to be done at night. A combination of isotropically reinforced...
Composite Sketch
Composite materials from the aerospace and military sectors are showing promise in highway, bridge and transportation applications. Some of the current and potential applications of composites...
Seismic Analysis of Bridges: Simplified or Refined Approach
This paper discusses the differences of seismic responses of bridges among various analysis methods and approaches....
Dynamic Loading of a Rigid Frame Bridge
The objective of this paper is to investigate the dynamic response of a rigid frame bridge to two trucks (side by side) passing over the rough bridge deck. The rigid frame bridge is designed...
Corrosion Resistant Epoxy-Coated Reinforcing Steel
Research conducted in the 1970s to evaluate and develop criteria for nonmetallic coatings to protect steel reinforcing bars embedded in concrete bridge decks from the corrosive action...
A Study of Jointless Bridge Behavior
The pressing need for maintenance free and low construction cost bridges, has increased the interest and activity in building integral or jointless bridges. The investigation of the behavior...
The Normandie Bridge
The Normandie Bridge will have one of the longest cable-stayed spans in the world, i.e. 856 m long. This paper briefly describes the design of the bridge, with the concrete access spans...
Wind Studies of the Owensboro Bridge, Kentucky
Wind tunnel studies on the Owensboro Bridge are described in this paper, including 1:50 scale sectional model tests and 1:160 scale aeroelastic model tests. Comparisons are presented and...
AISI-FHWA Model Bridge Test
The Model Bridge Study involved a large experimental test program to evaluate the behavior of a 0.4-scale model of a two-span continuous plate-girder bridge with modular precast prestressed...
Design and Field Performance of a Metal-Plate-Connected Wood Truss Bridge
This paper describes an on-going study on the design and performance attributes of an experimental wood-truss bridge. This is believed to be the first roadway bridge application of metal-plate-connected...
Bridge Condition Rating Using Fuzzy Sets and an Eigenvector of Priority Settings
A simplified methodology for combining the condition rating of the various elements of bridge components (deck, superstructure or substructure) is developed using a multi-attributive decision...
Historic Yorktown: New Bridge Keeps Old Design
In historic Yorktown, Va., the best solution to reconstructing an obsolete 1952 bridge was to keep its unique design while widening it for '90s traffic. Like the original,...
