A Grand New Bridge
Approximately 65 km south of Seoul, rising above the Asan Bay, the Seohae Grand Bridge now stands as the longest bridge in South Korea. The 9.4 km long cable-stayed bridge, which runs...

Out of the Way
The 0.9 mi (1.4 km) long Fort Washington Way was built in 1961 as a distributor for local downtown traffic. It quickly became a critical section of the region's Interstate...

Beltway Connection
The Woodrow Wilson Memorial Bridge carries the Capital Beltway (I-495) and a part of I-95�the main north�south interstate route on the East Coast�across the Potomac River south of Washington,...

Stronger Longer
Like many older concrete bridges, the Sierrita de la Cruz Creek Bridge, a 1957 crossing near Amarillo, Texas, suffered from concrete deterioration. When the Texas Department of Transportation...

Bell's Bridge Rehabilitation
Bell's Bridge carries Tidewater Drive, a major urban arterial in the City of Norfolk, Virginia, over Wayne Creek, a tributary of the Lafayette River. During a routine inspection in 1995,...

Seismic Design of Highway Bridges: Recommended Specifications
Under the AASHTO-sponsored National Cooperative Highway Research Program (NCHRP), a joint venture of the Applied Technology Council and the Multidisciplinary Center for Earthquake Engineering...

Magnetic Perturbation Imaging for Prestressed Concrete Evaluation
Many prestressed concrete bridge structures in the United States and other parts of the world are over thirty years old and have shown various signs of distress. Corrosion or fracture...

Cross-Frame and Diaphragm Behavior in Skewed Bridges
The author examines the existing specifications and guidance for bracing provisions by AASHTO, AISC, and TxDot, and the need for developing bracing requirements....

Maintenance of Diaphragm-Girder Connections
Fatigue cracking at diaphragm-girder connections and at similar connections of cross-frames and floorbeams have been common in steel highway bridges for the past 20 or 30 years. Fatigue...

A Framework for Performance-Based Seismic Design
The following probabilistic framework for seismic performance assessment is presented as an effective foundation for the development of performance-based guidelines. It suggests a generic...

Effect of Column-to-Beam Strength Ratio on Seismic Performance of RC Moment Frames
Reinforced concrete (RC) moment frames are often used in building applications. During strong earthquake excitations, such buildings have been subject to soft-story or column sidesway...

The Effect of the Slab on Beam-Column Joint Behavior
The three-dimensional effect of slab interaction on frame behavior has been observed in lateral load tests on beam-column-slab elements....

High Performance Dampers for Bridges
A multi-disciplinary research study investigates the use of shape memory alloys as seismic dampers in bridges. Shape memory alloys are a class of alloys that display several unique characteristics,...

New Developments in the Field of Seismic Isolation
This paper will concentrate onwhat likely, is the most significant of these issues: changes in the mechanical properties ofseismic isolation and energy dissipation hardware as they are...

Performance of Masonry in Disasters: Lessons Learned and Research Needs Identified
This presentation described in this extended abstract is one of several in a panel discussion entitled Enhanced Research in Masonry. The objectives of the presentation are to discuss the...

Seismic Analysis and Retrofit of the Amoskeag Bridges
In 1983 AASHTO first offered the design guide for seismic analysis of bridges, which ultimately became a permanent part of the AASHTO Bridge Design Manual in 1990. Prior to this time,...

Rehabilitation of the Packers Falls Bridge
The Packers Falls Bridge was constructed in 1912 and consists of a 42' (12.8m) single span, reinforced concrete arch structure. This bridge was constructed using a unique forming system...

Piece by Piece
The Lions' Gate Suspension Bridge, a landmark structure in Vancouver, British Columbia, marks the entrance to one of the busiest harbors on the west coast of North America....

Fast Forward
Under the aegis of the French government, the Soci�t� Nationale des Chemins de Fer Fran�ais (French National Railway Society), or SNCF, has built two new bridges, each approximately 1,100...
