Towering Over Xiamen (Available in Structural Engineering Special Issue only)
Composite structural systems are rapidly becoming the preferred choice for high-rise buildings, due to their high strength and stiffness, large ductility, and convenient, economical construction....
Back from the Brink
The Cape Hatteras Lighthouse, the tallest brick lighthouse in the United States, has been moved to prevent it from toppling into the sea as a result of coastal erosion. Engineers from...
On the Wild Side
Designers of today's roller coasters are constantly looking for new ways to exhilarate riders, from higher drops to tighter turns to launch mechanisms that exert more force...
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...
Considering the Options (Available in Structural Engineering Special Section only)
In work for the Missouri Department of Transportation (MoDOT), Sverdrup Civil, Inc. performed a seismic evaluation and developed a seismic retrofit strategy for the Poplar Street Bridge...
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...
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...
Ground Attack
Buried surfaces made of concrete, ductile iron and carbon steel are susceptible to corrosion by the soil that surrounds them, but there are numerous ways that these surfaces may be protected....
Muscle Made of Carbon Fiber
Carbon fiber reinforced plastic (CFRP) extends service life and increases load-bearing capacity when applied to concrete structures. CFRP is less expensive than traditional strengthening...
Downtown Goes Uptown in Stainless Steel
