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,...
Under Pressure
The Arrowhead East and West contracts for the Inland Feeder water conveyance system being built in California consist of 51,500 ft (15,700 m) of tunnels that cross the San Andreas Fault...
Main Line Mending
Both the Washington Suburban Sanitary Commission (WSSC), of Laurel, Maryland, and the Providence Water Supply Board, of Rhode Island, are conducting massive, multimillion-dollar rehabilitation...
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....
Evaluation of the ISOGRID Retaining Wall System
Prepared by the Highway Innovative Technology Evaluation Center, a CERF service center. This report presents the results of a HITEC evaluation of the...
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...
Tall Order
Successive earthquakes have damaged the 32-story, 460 ft (140 m) tall Los Angeles City Hall, built in 1926. Masonry infill and concrete walls have cracked, and the terra cotta cladding...
Evaluation of the SSL MSE PlusTM Retaining Wall System
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF service center. This report describes a HITEC evaluation designed to...
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....
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...
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...
Over the Top Concrete
The 60-year-old Tongue River Dam in southeastern Montana is undergoing extensive dam safety and reservoir enlargement modifications. Major features of the project include a 60,000 cfs...
Concrete Change
The concrete industry has an array of options when it comes to recycling. Incorporating glass, chicken feathers, palm fronds, sludge, crushed computer casings or other recycled materials...
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...
Casting Hot and Cold
Contractors and engineers battled the Minnesota winter to build a concrete segmental bridge with form travelers. Superstructure segments were poured in temperatures as low as -19F, using...
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...
Rock Dam Revitalization
