Abstract
In this study on the development of energy-dissipating devices, a significant component of the ring-net system was investigated for the localization of a high-performance rockfall fence and debris flow barriers. The energy-dissipating device was developed as a structure that dissipated the resistance and frictional forces generated by the pipe passing through two steel bars, and the tensile force was transmitted by utilizing the pipe deformation. The performance of the developed energy-dissipating device was verified through simulation analysis and tensile tests. It was confirmed that the most effective dissipating device was made of a D60.5-3.2t pipe subjected to a rolling interval of 40 mm, and the device exhibited an energy-dissipating performance of 52.8-60.2 kJ/m.
