Abstract
Exact application of the tensile force is critical to high-tension members in civil engineering structures, and thus actual tensile forces have often been estimated in field. To date, a few methodologies have been presented utilizing static and/or dynamic responses of tension members. Each of these methods has its disadvantages as well as advantages in its procedures, accuracy, and equipment requirements. In this paper, the feasibility of a sensitivity based methodology, based on the relationship between the natural frequencies and the applied tensile force, developed by the authors, is verified using the measured data from a cable-stayed bridge structure. From the results, it is shown that the proposed method can be utilized in estimating the tensile force in tension member of a real structure.
