Identity Crisis
For years, engineers have established the authenticity of original documents with stamps and signatures. Although stamps and signatures work well for hard copies of documents, they inadequate...
Site Investigations: A Guide (available in Geoenvironmental Special Issue only)
A geotechnical engineer looks at the evolution of reports on subsurface conditions, the most uncertain portion of construction. Most of the cost and risk of construction occurs beneath...
All Decked Out
After 50 years of wear, the deck of New York City's Williamsburg Bridge was buckling and badly in need of replacement. In 1994, consultants recommended replacing the deck...
Solid Footing (available in Geoenvironmental Special Issue only)

Cable-Stay Conundrum
Wind- and rain-induced vibrations of cables on cable-stayed bridges are a relatively new phenomenon. While some observers report hearing about such vibrations ten or 12 years ago, typically...
Preparing for Pier A
Earthquakes, oil wells, contamination and unstable soil were among the challenges engineers faced as they prepared a site at California's port of Long Beach for the Pier A...
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...
Mitigation of Void Development under Bridge Approach Slabs Using Rubber Tire Chips
The problem of void development under bridge approach slabs has been correlated to the use of integral abutment bridges (Schaefer and Koch, 1992). This void development then causes settlement...
Tire Shreds as Lightweight Fill for Embankments and Retaining Walls
Use of tire shreds in three highway projects is described. In the first project, tire shreds were used as a compressible inclusion to reduce pressures on a rigid frame bridge. Earth pressures...
Behavior of Construction and Demolition Debris in Base and Subbase Applications
The design performance of a pavement system is evaluated based on the predicted number of load repetitions it will be subjected to throughout its service life. Mechanistic pavement design...

Coldhearted Building
A 20,000-ton district cooling plant owned by the Public Service Company of Colorado was recently built to sell chilled water to customers in downtown Denver who will use it to air-condition...
Hydraulics of Open Channel Flow
This text is designed to make a deliberate effort to extend the modern fluid mechanics approach into the analysis of open channel flow without necessarily requiring the use of advanced...
Sky High
The increasing demand for personal communication services (PCS), such as digital cell phones and pagers, as well as digital television (DTV), has created new challenges for creating and...
