Experimental research on the bending performance of locked coil wire rope and Galfan strand
Highlights The paper carried out bending tests on locked coil wire ropes and Galfan strands. Obtain the bending performance and effective bending stiffness of the cables. For prestressed cables, the geometric stiffness is dominant. The paper proposed the prediction method of effective bending stiffness.
Abstract As a key component in prestressed structures, the bending stiffness of a cable significantly affects the dynamic response characteristics, such as vibration control and cable tension measurements using the vibration method. Based on the beam theory, this study reports experimental results on the bending performance of locked coil wire ropes and Galfan strands. Quasi-static bending tests under different end treatments and prestress levels were conducted, using four common specifications of locked coil wire ropes and three specifications of Galfan strands, to infer the effective flexural rigidity and to study the flexural performance of the cables. The results show that the load-deformation curves of unprestressed cables are bilinear, which is similar to that of a simply supported beam. The physical stiffness of the prestressed cables is not obvious. The geometric stiffness produced by the prestress dominates, and the effective stiffness coefficient can exceed 1000. Based on the Papailiou theory and beam theory, a predictive model is proposed for predicting the bending stiffness of cables under high prestress conditions. This model provides a reference for bending stiffness predictions of cables.
