Good vibrations

With little work and high accuracy, using laser-based vibration measurement for the calculation of tension forces in cable-stayed bridges can be achieved quickly, as explained in this article. Because stay cables are not thoroughly inspected on a regular basis, especially for older structures with cable systems containing grouted elements, it is crucial that bridge owners are able to have confidence in extending the life of this essential structural element. Since the resting method is non-contact and non-invasive, no instruments need to be attached to the cable, nor is there a need for direct access to the cable being measured.
