Field Measurement of Cable Tension Using Energy Method
For existing cable structures, vibration frequency method (VFM) seems to be the common way to determine the tensile force of the cables. However, the applicability of this method is limited by the specific conditions of cables. Only well tensioned slender cables with simple boundary conditions can be measured through VFM directly without causing much error. In this paper, the vibration mode of the cable is measured and then cable tension is calculated via energy conservation principle.
