Abstract

It is necessary to estimate the dynamic characteristics of stay cables ie., the natural frequencies and the damping ratios of the stay cables to design cable damper for appropriate mitigation of cable vibrations and/or to estimate the tension of cables in service. In this study, a cable exciting robot for evaluating dynamic characteristics of stay cables has been developed, and the feasibility of the developed system has been demonstrated through a field test on the stay cable installed at the test yard of Highway and Transportation Technology Institute (HTTI). The dynamic characteristics of the stay cable were estimated based on acceleration data as well as displacement measured by digital image processing technique.
