    • Abstract
  • In order to investigate the bending behaviors of CFRP cable in the saddle and clamp, the bending properties of the cable depending on CFRP rods is theoretically analyzed, then two different bending behaviors of CFRP rods in the saddle and clamp are also theoretically analyzed. The bending-resistance efficiency is presented and parametric analysis on the factors affecting the bending resistance efficiency is conducted. Furthermore static tests are carried out under different loading. Theoretical and experimental results show that the bending resistance efficiency behaves linearly with change of the ratio of the CFRP rod radius and bend radius. Smaller ratio provides higher the bending resistance efficiency. The bending angle and CFRP ultimate strain affect bending resistance efficiency significantly at higher ratio of CFRP rod radius and bend radius. The bending resistance efficiency can reach more than 90% in the test. The results of theoretical analysis agree well with those of the experiment.
