Super-Bridges Suspended Over Carbon Nanotube Cables
Alberto Carpinteri, Nicola M. Pugno
TL;DR
This paper introduces the concept of super-bridges suspended over carbon nanotube cables, demonstrating that realistic nanotube bundles can significantly extend bridge span lengths beyond current limits.
Contribution
It presents a novel concept of super-bridges and analyzes how defective carbon nanotube bundles can be used to greatly increase bridge span lengths.
Findings
Carbon nanotube bundles can triple the maximum span of bridges.
Super-bridges are feasible with realistic, defective nanotube cables.
The concept opens new possibilities for large-scale structural engineering.
Abstract
In this paper the new concept of super-bridges, i.e. kilometre-long bridges suspended over carbon nanotube cables, is introduced. The analysis shows that the use of realistic (thus defective) carbon nanotube bundles as suspension cables can enlarge the current limit main span by a factor of 3.
