Bump At the End of the Bridge
Interface bumps between bridge abutments and embankments increase risk and add over $100 million to maintenance expenses every year. New research reveals effective ways to deal with the...
A Signature Bridge for Boston (Available only in Structural Engineering Special Issue)
The first hybrid steel and concrete span in America will debut over the Charles River in Boston, carrying ten lanes of interstate traffic and serving as an elegant capstone to the largest...
Braced for Failure (Available only in Structural Engineering Special Issue)
Investigations into the collapse of steel-framed structures often focus on minor, insignificant design flaws, only to ignore the real culprit: inadequate temporary bracing. The collapse...
Full Use of Arching in Deck Slabs (Available only in Structural Engineering Special Issue)
The use of arching concrete deck slabs allows engineers to safely reduce the amount of reinforcement at a significant overall cost savings. Engineers with the Ministry of Transportation...
Fathoming the Strength of Structures
More and more, the owners of bridges and piers are budgeting rehabilitations based on inspections done underneath the waterline. Increasingly, they want the underwater inspectors to be...
The Evolution of Geosynthetics
Although the geosynthetics industry only began in the 1960s, it roots can be traced to the earliest humans. Soil stabilization, soil reinforcement, liquid drainage and leak proof barrier...
