Post-Tensioned Foundations as Economical Alternative
Although post-tensioned (p-t) foundations have been utilized in the U.S. since the early 1960s, the last five years have witnessed a substantial increase in their implementation. Used...
The Concrete Canoe: A Technological Challenge
In 1970 the first concrete canoe was built, and since that time many colleges and universities have built and raced concrete canoes. The Union College (Schenectady, NY) Stone Boat Club...
How about Reverse Filters
Reverse or inverted filters allow water to drain freely without carrying away suspended solids. Their pore size must be properly related to the fines being protected. Terzaghi's...
Basics in Failure Analysis of Large Structures
Failure analysis procedures can usually determine the most probalbe cause of a structural failure. Then it is possible to determine why the initial design, materials selection, and fabrication...
Venezuelan Dock Features Unconventional Design, Quick Set-Up
This structure, designed by Caracas design/construct firm Precomprimido, kills two birds with one stone: a series of huge, hollow concrete cylinders both support the service deck of the...
Inspecting Dam Construction
Through and competent inspection during construction is crucial to assure dam safty. Inspection for dam construction is more important than for other types of structures because plans...
Some Secrets to Building Structures on Expansive Soils
Each year, in the U.S. alone, shrinking or swelling soils inflict over $ 2.3 billion in damages to houses, buildings, roads, pipelines, and other structures. Despite this many engineers...

Faults in Swedish and American Tunnel Practice: A Fable
Swedish and American practices in dealing with unanticipated geological conditions encountered during tunnel construction are contrasted. Swedish practice, illustrated with an actual example,...
Surveying Takes Another Giant Step Forward
The introduction of short-range electronic distance measurement in 1971 revolutionized surveying. Thousands of surveying and engineering firms across the U.S. today routinely use EDM for...
Ontario Writes New Bridge Code
In 1976, Ontario's Ministry of Transportation and Communications decided to write its own bridge design code, breaking away from the AASHTO code, because: (1)It wanted a metric...
Design and Construction of Long-Span Metal Culverts
Long-span metal culverts are built of corrugated-metal plates bolted together. They have spans exceeding 15 ft. Principal applications include use as drainage structures, grade separations,...
Building Skyscrapers in Orbit
NASA plans to build a host of large structures (communications antennas, remote-sensing radiometers, solar power satellites, etc.) in space. Three ways to build them are: (1)Fabricate...
Best Ways to Dewater Dredged Material
Left to its own devices, fine-grained dredged material placed in confined disposal areas reaches an equilibrium water content near its Atterberg liquid limit. The high water content of...
