Cable Access
By moving the expansion joints off the main, cable-stayed span and creating innovative cable connections and tower configurations, Parsons Brinckerhoff Quade & Douglas Inc. (PB)...
Cap of Concrete
The roof of a new $84 million arena in New Orleans was built using techniques usually seen in tied-arch concrete bridges. The concrete components of the roof carry the large compression...
Suspension Bridges Unplugged
The `coupling effect' between the flexible, suspended superstructure and the very stiff cable anchorage in suspension bridges can produce large motions during strong earthquakes....
Forging Ahead
More than a dozen bridges in the United States have been built using HPS 70W grade steel, which has a yield strength of 485 MPa (70 ksi) but superior toughness compared to conventional...
Covered Bridge Connection (Available in Structural Engineering Special Issue only)
A 145-year-old timber bridge in Downsville, New York, now rests on the longest glue-laminated wood beams ever produced in the United States. Six 53 m (174 ft) long chords were threaded...
Substructures Stack Up (Available in Structural Engineering Special Issue only)
As part of a 1997 research project sponsored by the Texas Department of Transportation and the Federal Highway Administration, the University of Texas at Austin Center for Transportation...

Sizing Up Seismic Bearings
Today in the U.S., there are two general technologies available to protect new and existing bridges from the damaging effects of earthquakes. One type, seismic isolation bearings, provide...
Keeping a Low Profile
The Admiral Clarey Bridge in Pearl Harbor, Hawaii, combines fixed and floating bridge elements to span more than 4,500 ft (1,372 m) while hovering just above the harbor waters. The bridge,...
Bridge Safety and Reliability
Sponsored by the Structural Engineering Institute of ASCE. This report covers a wide range of applications of modern structural safety and reliability...
Stream Stability and Scour at Highway Bridges
Compendium of Stream Stability and Scour Papers Presented at Conferences Sponsored by the Water Resources Engineering (Hydraulics) Division of the American Society of Civil Engineers
Sponsored by the Water Resources Engineering (Hydraulics) Division of ASCE. This collection contains 75 papers and 321 abstracts presented at conferences...
The Arch Bridge Mystery
For some years, concrete from the Manayunk Bridge�a long-idle, spandrel-arch railroad bridge in Philadelphia�had been spalling toward the streets and river below. While a system of nets...
Construction Control for Earth and Rockfill Dams
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 27 This manual provides critical guidance for constructors...
Seattle Solutions
Many of Seattle's most important bridges are vulnerable to serious damage if a much-anticipated big earthquake hits. A city-wide study designated lifeline structures for retrofitting,...
Advancing Composites (Available in Structural Engineering Special Section only)
Advanced composites, particularly fiber-reinforced polymers, have received considerable attention from bridge owners over the last few years, as cost-effective, durable alternatives to...
Calendar: Bridges 2000 Calendar
Featured bridges are: Mill Creek Park Suspension Bridge (OH); Coos Bay (McCullough Memorial) Bridge (OR); Gothic Arch (NY); Bidwell Bar Suspension Bridge (CA); Plaza de Espana (Spain);...
A Composite Sketch
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...
High-Performance Powder
The application of fundamental principles related to the composition, the making, and the thermal treatment of concrete resulted in the development of a new type of concrete with outstanding...
Mix and Match
The U.S. Navy wanted to expand operations at Pearl Harbor, which required a bridge from Oahu to nearby Ford Island. The bridge spans more than 4,000 ft, and combines a fixed bridge and...
Balancing Act
The cable-stayed $69 million Glebe Island Bridge in Sydney was built using a combination of one rolling frame and one form traveler instead of a more orthodox two or four form traveler...
