Brittleness Index of Cementitious Composites
Series of direct tension tests were conducted to observe the softening response of different types of cementitious composites, namely, mortar, plain concrete, high strength concrete, normal...

Composite Applications in Highway Bridges
This report presents a summary of a four year research effort titled, 'Transfer of Composite Technology to Design and Construction of Bridges'. Extensive analytical...

Laboratory Fatigue Investigation of a GRP Bridge
A fatigue study of a 4.9 m glass-reinforced plastic bridge indicated a resistance to 1.6 million cycles of load without extensive damage to joints or elements. Viscoelastic creep occurred...

Concepts for Hybrid FRP Bridge Deck Systems
This paper presents selected structural concepts for modular bridge deck systems taking into account the limitations imposed by fabrication processes for polymer matrix composites. An...

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...

Fatigue Behavior of Bond-Anchored Unidirectional Glass-FRP's
The contribution reports on the fatigue behavior of fiberglass reinforced plastic (FRP) bars, consisting of endless E-glass fibers embedded in a polyester (PE) matrix and anchored in a...

Uni- and Bi-Axial Compressive Fatigue of Fiber Concrete
Fatigue behavior of fiber reinforced concrete is studied under uniaxial and biaxial loadings. The S-N curves and the cyclic deformations of fiber concrete are compared to those of plain...

Flexural Behavior of Synthetic Fiber Reinforced Rapid Set Materials
This paper presents the results of a laboratory investigation on the contribution of synthetic fibers to the flexural behavior for three typical rapid set materials. Three types of synthetic...

Major Development and Transportation Projects
Public/Private Partnerships
This proceedings for Major Development and Transportation Projects contains papers and discussion summaries from the specialty conference Major Development and Transportation Projects:...

World's Largest Caisson
The world's largest caisson (210,000 cy) forms the offshore cable anchorage for the 1,870 ft main span Tokyo Harbor Bridge. The bridge carries Metropolitan Expressway Route...

Facelift For an Interchange
The authors describe a $250 million reconstruction project on a three-level interchange linking I-84 and I-91 in Hartford, Conn., which is the largest rehabilitation project in the state's...

U.S. Landmarks: Handle With Care
Landmarks are treated with kid gloves during restoration, but striking a balance between costs and aesthetics is difficult. In addition to structural integrity, original construction methods...

Replacing Bridge Decks
U.S. bridges last an average of 68 years, their decks 35 years. But few bridges have been built with provisions for future deck repair, the only criterion being lowest first cost. During...

Bridges on Screen
Computer software can help engineers produce designs for more economical, constructable bridges in less time than conventional methods. Software is being put to work in bridge design departments...

Building Blocks for the Future
In the near term, advanced, conventional materials�namely higher-strength steel and concrete�will dominate infrastructure rehab. New steels of higher strengths and toughness are increasingly...

The Invisible Engineer
For all their contributions to society, engineers have worked largely behind the scenes, seldom remembered in the dedication ceremonies of bridges and tunnels and skyscrapers. Several...

Structures Congress Abstracts 1990
Abstract only. The following themes are included: Rehabilitation and future challenges, Bridges, Earthquake engineering, Dynamic loads on structures, Metals and composite construction,...

Ambient Vibration Tests of a Suspension Bridge
Originally published in: Journal of the Engineering Mechanics Division, ASCE, EM5, October 1978, pp. 983-999...

Wind Bracing
This chapter discusses the structural design of the bridge with regards to wind forces....

The Abutments and the Structural Defect
This chapter discusses the bridge's abutments....
