Molecular forces: The surprising stretching behavior of DNA

When large forces act on a heavy beam, for example, in bridge construction, the beam will be slightly deformed. Calculating the relationship between forces, internal stresses and deformations is one of the standard tasks ...

Achieving strong structures with carbon fiber reinforced plastics

Researchers of the Structural Engineering Laboratory, Department of Architecture and Civil Engineering, Toyohashi University of Technology have developed a new concept for strengthening steel in critical building structures ...

How transit scaling shapes cities

The research, published in Nature Sustainability, analyzed data collected from 48 metropolitan areas in the United States, including New York, Boston, Minneapolis and Atlanta, which showed a positive correlation between ridership, ...

A more sustainable material to reinforce concrete structures

The next generation of ultra high-performance fiber-reinforced concrete (UHPFRC) has just been created at EPFL. The new material will be used to strengthen and to extend the life span of bridges and other structures—both ...
