Above Them All
The design for what would be the next world's tallest building relies on a 1,550 ft (472 m) high concrete core that will give occupants of the top floors of the building unimpeded...
Space Truss
The International Space Station will be more than 310 ft (94 m) long when it is completed sometime in the next decade. The backbone of the structure is a hexagonal truss system that will...
From Pikes Peak to Mars
A graywater (sink and shower wastewater) reuse system is now being designed to serve a visitors' center and a nearby laboratory atop Pikes Peak, Colorado. If the Pikes Peak...
The California Experience
With a terrain that ranges from the highest mountains to the lowest deserts, from salt marshes to beaches, from sierra to plateau, the natural environment that challenges the California...
Glass Nautilus
A multi-faceted glass and steel pavilion now adds an extra measure of enjoyment and convenience for visitors to Seattle's Space Needle. The new two-story, 15,000-square-foot...

Domesticating Steel
Residential contractors, nervous about fluctuations in lumber prices and quality, would welcome steel framing into the housing market if the necessary infrastructure were in place. Despite...
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...
Framing a Work of Art
One of the most visually unique building designs of the twentieth century, the Guggenheim Museum project in Bilbao, Spain, required an innovative structural engineering solution and pioneering...
Federal Triangle Finale
At 3.1 million sq ft, the Ronald Reagan Building and International Trade Center is the second largest U.S. federal building ever constructed; only the Pentagon is larger. After more than...
A Museum for the Heavens
Replacing a icon such as the Hayden Planetarium's thin-shelled concrete dome is not the most desirable assignment. But the design team for the new Frederick Phineas and Sandra...
Cellar Performance (Available in Structural Engineering Special Issue only)
Even though the Pentagon contains three times the square footage of the Empire State Building, free space has become hard to come by. Expanding computer, mechanical and electrical systems...
Test Wall Promises Big Savings (Available in Geo-Environmental Special Issue Only)
A new kind of retaining wall is being tested in Texas at a National Geotechnical Experiment site. The wall is a variation of soil-mixing that uses fewer columns, which saves time, materials...
Concrete Colossus
After finding 120 million cubic meters of oil and 30 billion standard cubic meters of natural gas 175 kilometers off the Norwegian coast, Houston-based Conoco, Inc. was faced with a second...
A Dual Answer to Seismic Stress (Available only in the Structural Engineering Special Issue)
Are two systems better than one? When it comes to high-rise seismic design post-Northridge, the answer may be yes, based on studies conducted by CBM Engineers, Inc., Houston. The aftermath...
