WIRED STRUCTURE COLLECTS EVIDENCE

This brief article reports on a new fiber optic material being tested by researchers at Tennessee's Oak Ridge National Laboratory. The fiber can be embedded in concrete beams and slabs to test long-term stress. Appropriate for new construction only, the system could have wide use in buildings, bridges, and other large structures. The new silicone rubber cables are more elastic and sensitive to pressure, heat, and moisture than standard cables. Researcher Jeffrey Muhs reveals that the changes in pressure, bending, and stretching affect the amount of light transmitted through the fiber optic cables, allowing scientists to monitor the condition of the cable. The system could also be used in concrete slabs to test for cracking and deformities. Initial test results should be available in two or three months.
