| Abstract: |
| In engineering practice,sliding of a cable at a cable-strut joint is common.Because of sliding,a cable strut joint cannot be simply represented by a hinge.The existing analytical methods for cable sliding needs iteration,whose calculation process is complex and convergence cannot be guaranteed.This work proposes a novel sliding variable method to analyze cable sliding.The pre-stressed fish-belly beam is utilized to demonstrate the theoretical derivation.Meanwhile,the basic principle and calculation steps are clarified.Based on a finite element software package,a numerical experiment is conducted using the sliding variable method.The results show that the sliding variable method is fast and does not need iteration,and the cable sliding can be analyzed more accurately. |
