Numerical and Experimental Study on Anti-slipping Performance of Cable Clamp for Two-Way Orthogonal Full Locked Coil Cables

다국어 초록 (Multilingual Abstract)

The cable structure has been widely adopted in some engineering applications. Cable clamp and its anti-slipping performance is the key factor to assure the bearing capacity for cable structure. This paper is concerned with the slipping resistance between cable clamp and Z shape full locked coil cables in a two-way orthogonal cable-net structure. Firstly, a new method for laboratory test of the clamp is designed, which is carried out under cable tension. The clamping force of high-strength bolt and the pushing force are monitored in real time. According to force reaction–displacement graphs obtained from the test, the reasonable anti-slipping ultimate frictional force of the clamp is determined and the precise friction coeffi cient of the clamp is calculated by the data from real-time monitoring. Finally, through the simulation analysis of nonlinear fi nite element model, the results are basically consistent with the laboratory test. The proposed method can be extended to solve anti-slipping problems of similar cable clamps.
