Efficient structures help build a sustainable future

When envisioning a new structure, engineers often have to balance design choices against the environmental impact of materials used. It is estimated that 40 to 50 percent of greenhouse gases are produced by the construction ...

WorldÂ’s first commercial nanostructured bulk metal

When we think of structural materials, we usually imagine something big, strong and bulky, like steel beams in bridges and buildings, and while we are becoming familiar with composites reinforced with carbon nanotubes and ...

Steel quality optimized 3-D technology

An innovative method for the quality inspection of hot surfaces is used on an industrial level for the first time: A major Turkish steel producer is optimizing the production of high speed-compatible rails with the method ...

Cold-formed steel rebuilds earthquake-resistant architecture

Academia and industry are collaborating in a new effort to engineer earthquake-ready buildings. The effort based at Johns Hopkins University aims to design and test a single structure primarily built from cold-formed steel, ...

New fatigue model leads to more durable ships

Heikki Remes at the Aalto University School of Engineering, Department of Applied Mechanics, has developed a model making it possible to determine how fatigue sets in with various welded steel materials. The model allows ...

'Shaky' plan: Quake experiments may lead to sturdier buildings

Cold-formed steel has become a popular construction material for commercial and industrial buildings, but a key question remains: How can these structures be designed so that they are most likely to remain intact in a major ...
