Abstract

<p>It is known that chain link wire netting, which is used as one of the energy-absorbing components of rockfall protection structures, undergoes partial strain hardening due to plastic processing during manufacture and shows anisotropy in terms of deformation properties. It is necessary to confirm the mechanical similarity of chain link wire netting with these characteristics in order to carry out reduced-scale model experiments of rockfall protection structures in the future. In this study, as a fundamental study, reference dimensions (full scale) and reduced model specimens of chain link wire netting were fabricated and statically tested in the in-plane and out-of-plane directions of the chain link wire netting. Numerical analyses of the experimental results were also carried out. The experimental and analytical results confirmed the mechanical similarity of the rhombic wire mesh according to the replica law, based on the load-deformation relationship of each test and the load-tension relationship at the wire mesh constraint.</p>
