Raising the Bar of BART
Although it was originally designed to withstand a strong earthquake, and did so admirably in 1989, the Bay Area Transit (BART) system was recently evaluated to determine its ability to...
Space Truss
The International Space Station will be more than 310 ft (94 m) long when it is completed sometime in the next decade. The backbone of the structure is a hexagonal truss system that will...
The Collision of Surf, Sand, and the Law at Lechuza Beach: Coastal Processes and Public-Private Shore Boundaries
In order to undertake coastal development opportunities, the property owner must first establish the boundary between public and private property along the beachfront in order to demonstrate...
Safeguarding Los Alamos
A forest fire that burned 48,000 ac (19,500 ha) around the Los Alamos National Laboratory, in New Mexico, in May 2000, created another problem for one of the nation's most...
Best of Both Worlds
All around the Pacific Rim structural engineers are experimenting with concrete filled steel tubes as structural elements. The concrete filled tubes take advantage of the best properties...
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...
Finding the Right Bond
Professors and students from a Swiss university built a dual-span glass fiber reinforced polymer (FRP) bridge to gain a better understanding of how composite materials behave and how best...
Suspension Bridges Unplugged
The `coupling effect' between the flexible, suspended superstructure and the very stiff cable anchorage in suspension bridges can produce large motions during strong earthquakes....

Potential Climate Change Effects on Great Lakes Hydrodynamics and Water Quality
This report provides a state-of-the-art review of the climate change effects on lake hydrodynamics and water quality. Most of the engineering cases in this book deal with the ability of...
Sizing Up Seismic Bearings
Today in the U.S., there are two general technologies available to protect new and existing bridges from the damaging effects of earthquakes. One type, seismic isolation bearings, provide...
Recent Advances in the Characterization of Transportation Geo-Materials
This proceedings,
Electrical Explorations (Available in Geo-Environmental Special Issue only)
Recent advances in state-of-the-art, relatively fast, two- and three-dimensional electrical resistivity imaging (also called profiling or tomography) have offered a new view on subsurface...
Behavioral Characteristics of Residual Soils
This proceedings,
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...
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...
Tough Conditions, Innovative Solutions
Two major innovations in U.S. construction practice are part of the solution to a complex and difficult portion of the Massachusetts Highway Department's Central Artery/Tunnel...
Geotechnical Performance of a Highway Embankment Constructed Using Waste Foundry Sand
A highway embankment was constructed near Auburn, Indiana, using waste foundry sand (WFS) as a demonstration project for the Indiana Department of Transportation (INDOT). Laboratory testing...
Recycled Materials for Embankment Construction
Obtaining good quality soils at reasonable costs for use in embankment construction is becoming difficult and hence, attention is directed towards finding alternative materials. On the...
Utilization of Lagoon-Stored Lime in Embankment Construction
The maximum percentage of lime that can be mixed with a predetermined borrow material to build the proposed road embankment without adversely affecting the physical and mechanical properties...
