Flexural Behavior of Slender Post-Tensioned Masonry Walls
The 2002 edition of the Masonry Standards Joint Committee (MSJC, 2002) design provisions for masonry structures includes a chapter on the design of post-tensioned masonry (PTM) walls with...
Special Structures: Past, Present, and Future
Enduring Strength
The long-term effectiveness of posttensioning in bridges depends on the resiliency of the tendons, and various factors related to construction and marine environments come into play. How...

Keeping It Together
A new framing system for precast concrete columns and beams will allow tall buildings to withstand large earthquakes without damage to the structural integrity of the building. By using...
Replacing the East Bay Bridge
The seismically vulnerable East Span of the San Francisco-Oakland Bay Bridge will be replaced with a dual eastbound and westbound, 3.6-km-long structure. The cost of the replacement bridge...
Special Geotechnical Testing: Central Artery/Tunnel Project in Boston, Massachusetts
The Central Artery/Tunnel Project (CA/T) in Boston, Massachusetts, is the largest urban highway construction project in the history of the interstate system. The magnitude and complexity...
Scheduled Departure
A busy, growing international airport constructs a new international terminal with upper and lower level access roads and expands its parking garage without interrupting services. The...
Stressing Masonry's Future
Post-tensioning techniques are expanding the possibilities for masonry in building and bridge construction. Two projects in Britain and the U.S. show the rewards of rethinking approaches...
Building Tension in Buffalo
The National Hockey League's Buffalo Sabres have a new home, topped with an unusual tension-braced domed roof. An ingenious combination of dome designs, the Marine Midland...
Getting Into the Act
The authors present a plan for giving successful presentations and suggest that presenters need to be more aware of presentation style and more scrupulous about chosing, crafting and honing...
Translucent Structural Beacon
In East Los Angeles some 2,000 children, teens and adults are accessing their future inside a building that is as high-tech as the computers they are using to learn. The 40,000 sq ft building...
New Block Copolymers for Membrane Materials
New fluorine containing polymer materials, which contain n-fluoro octylacrylate (pFOA) or n-fluorooctylmethylacrylate (pFOMA) repeating units, are being explored for use in thin film composite...
Monitoring Prestressed Structures
Developments in remote-monitoring technology provide new options for cost-effective management of prestressed and post-tensioned reinforcement systems. A case study shows how engineers...
Swimming in Style
The Deerfield Academy's new $10 million swimming and squash facility, built in the floodplain of a river, is a jewel-box created from glue-laminated timber, galvanized steel,...
Parking Lot Corrosion Cure
The $3 million structural repair and restoration of a large post-tensioned parking structure required engineers to replace 2,400 tendons while keeping the parking garage in service. After...
Bullwinkle's Big Brother
In 1980, the Outstanding Civil Engineering Achievement Award went to Cognac, Shell Oil Co.'s then-tallest offshore platform. In 1989 the Bullwinkle platform became the new...
