Digging for Answers (Available in Geoenvironmental Engineering Special Issue only)
Research at the six facilities that make up the National Geotechnical Experimentation Sites (NGES) has included tests on minipiles, groups of driven piles, shafts drilled in rock, and...
Testing the Load (Available in Geoenvironmental Engineering Special Issue only)
The Pittsburgh District of the U.S. Army Corps of Engineers recently began construction of a new gated dam to replace a nearly 100-year-old concrete fixed-crest dam on the Monongahela...
Environmentally Friendly Transport of Reservoir Sediment for Beach Nourishment with EDDY Pump
Sand impounded behind hydroelectric, flood-control and debris dams not only diminishes the intended function of the reservoir, but also starves downstream coastline by denying natural...
Wireless Warnings
Formwork failures cause dozens of construction-related deaths per year, but most can be avoided by adequate monitoring. The problem is, most monitors must be hard-wired to a computer on...
Towers in Motion (available in Structural Engineering Special Section only)
Undersea towers are typically designed to rigidly resist the forces of water and wind. But one type of tower is designed to be flexible and, rather than rely on its platform strength to...
Taking a New Approach (available in Structural Engineering Special Section only)
The first bridge rehabilitation project in Washington, DC to use the AASHTO Load and Resistant Factor Design (LRFD) specification reveals several lessons to be learned from using the newly...
Communicating in a Crisis
As professionals following the strictest ethical standards, civil engineers are entrusted with safety and well-being of the public, regardless of the scale or range of their designs. By...
Examining the Capitol Dome
The dome of the United States Capitol, designed and built from the 1850s to the 1860s, is a masterpiece of 19th-century engineering and construction. The majority of the dome is made of...
Design Live Loads for Parking Garages
The objective of this research project is to obtain a better understanding of parking garage live loads and to recommend an appropriate value for design. A load survey was conducted in...
Foundation Design for the Elevated Station
The Amundsen-Scott South Pole Station is located at an elevation of 2,850 m on the 3,200 m thick polar plateau, a field of ice and snow that is moving toward the ocean at a rate of 10...
Weighing Anchors
Modern anchorage systems offer design engineers and contractors unprecedented choice in load transfer mechanisms. Some anchors are highly specialized, while others are appropriate for...
Bridging Substance with Style
Engineers used an elegant form to come up with a functional solution when designing the new Damen Avenue Arch in Chicago. Two steel ribs, created using heat induction bending, closely...
Structural Surgery
Structural engineers had to transform four existing buildings and two new buildings into a new non-profit center for Jewish history. The buildings were of varying ages and had different...
